ip mroute

ip mroute [add|del] <dst-ip-addr>/<width> [table <table-id>] [rpf-id <ID>] [via <next-hop-ip-addr> [<interface>],

This command is used to add or delete IPv4 or IPv6 multicast routes. All IP Addresses (<dst-ip-addr>/<width>, <next-hop-ip-addr> and <adj-hop-ip-addr>) can be IPv4 or IPv6, but all must be of the same form in a single command. To display the current set of routes, use the commands show ip mfib and show ip6 mfib. The full set of support flags for interfaces and route is shown via; show mfib route flags and show mfib itf flags respectively. Example of how to add a forwarding interface to a route (and create the route if it does not exist)

ip route [add|del] [count <n>] <dst-ip-addr>/<width> [table <table-id>] via [next-hop-address] [next-hop-interface] [next-hop-table <value>] [weight <value>] [preference <value>] [udp-encap <value>] [ip4-lookup-in-table <value>] [ip6-lookup-in-table <value>] [mpls-lookup-in-table <value>] [resolve-via-host] [resolve-via-connected] [rx-ip4|rx-ip6 <interface>] [out-labels <value value value>] [drop]

This command is used to add or delete IPv4 or IPv6 routes. All IP Addresses (<dst-ip-addr>/<width>, <next-hop-ip-addr> and <adj-hop-ip-addr>) can be IPv4 or IPv6, but all must be of the same form in a single command. To display the current set of routes, use the commands show ip fib and show ip6 fib.

Example of how to add a straight forward static route:

ip route add 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0

Example of how to delete a straight forward static route:

ip route del 6.0.1.2/32 via 6.0.0.1 GigabitEthernet2/0/0

Mainly for route add/del performance testing, one can add or delete multiple routes by adding 'count N' to the previous item:

ip route add count 10 7.0.0.0/24 via 6.0.0.1 GigabitEthernet2/0/0

Add multiple routes for the same destination to create equal-cost multipath:

ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0

ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0

For unequal-cost multipath, specify the desired weights. This combination of weights results in 3/4 of the traffic following the second path, 1/4 following the first path:

ip route add 7.0.0.1/32 via 6.0.0.1 GigabitEthernet2/0/0 weight 1

ip route add 7.0.0.1/32 via 6.0.0.2 GigabitEthernet2/0/0 weight 3

To add a route to a particular FIB table (VRF), use:

ip route add 172.16.24.0/24 table 7 via GigabitEthernet2/0/0

To add a route to drop the traffic:

ip route add 172.16.24.0/24 table 100 via 127.0.0.1 drop

set interface ip address

set interface ip address [del] <interface> <ip-addr>/<mask> | [all]

Add an IP Address to an interface or remove and IP Address from an interface. The IP Address can be an IPv4 or an IPv6 address. Interfaces may have multiple IPv4 and IPv6 addresses. There is no concept of primary vs. secondary interface addresses; they're just addresses.

To display the addresses associated with a given interface, use the command show interface address <interface>.

Note that the debug CLI does not enforce classful mask-width / addressing constraints.

An example of how to add an IPv4 address to an interface:

set interface ip address GigabitEthernet2/0/0 172.16.2.12/24

An example of how to add an IPv6 address to an interface:

set interface ip address GigabitEthernet2/0/0 @::a:1:1:0:7/126

To delete a specific interface ip address:

set interface ip address del GigabitEthernet2/0/0 172.16.2.12/24

To delete all interfaces addresses (IPv4 and IPv6):

set interface ip address del GigabitEthernet2/0/0 all

Implementation: add_del_ip_address

set interface ip source-and-port-range-check

set interface ip source-and-port-range-check <interface> [tcp-out-vrf <table-id>] [udp-out-vrf <table-id>] [tcp-in-vrf <table-id>] [udp-in-vrf <table-id>] [del]

Add the 'ip4-source-and-port-range-check-rx' or 'ip4-source-and-port-range-check-tx' graph node for a given interface. 'tcp-out-vrf' and 'udp-out-vrf' will add to the RX path. 'tcp-in-vrf' and 'udp-in-vrf' will add to the TX path. A graph node will be inserted into the chain when the range check is added to the first interface. It will not be removed from when range check is removed from the last interface.

By adding the range check graph node to the interface, incoming or outgoing TCP/UDP packets will be validated using the provided IPv4 FIB table (VRF).

@note 'ip4-source-and-port-range-check-rx' and 'ip4-source-and-port-range-check-tx' strings are too long, so they are truncated on the 'show vlib graph' output.

Example of graph node before range checking is enabled:

show vlib graph ip4-source-and-port-range-check-tx

           Name                      Next                    Previous
ip4-source-and-port-range-      ip4-drop [0]

Example of how to enable range checking on TX:

set interface ip source-and-port-range-check GigabitEthernet2/0/0 udp-in-vrf 7

Example of graph node after range checking is enabled:

show vlib graph ip4-source-and-port-range-check-tx

           Name                      Next                    Previous

set interface ip table

set interface ip table <interface> <table-id>

Place the indicated interface into the supplied IPv4 FIB table (also known as a VRF). The FIB table must be created using "ip table add" already. To display the current IPv4 FIB table, use the command show ip fib. FIB table will only be displayed if a route has been added to the table, or an IP Address is assigned to an interface in the table (which adds a route automatically).

@note IP addresses added after setting the interface IP table are added to the indicated FIB table. If an IP address is added prior to changing the table then this is an error. The control plane must remove these addresses first and then change the table. VPP will not automatically move the addresses from the old to the new table as it does not know the validity of such a change.

Example of how to add an interface to an IPv4 FIB table (where 2 is the table-id):

set interface ip table GigabitEthernet2/0/0 2

Declaration: set_interface_ip_table_command src/vnet/ip/lookup.c line 749

Implementation: ip4_table_bind_cmd

set interface ip6 table

set interface ip6 table <interface> <table-id>

Place the indicated interface into the supplied IPv6 FIB table (also known as a VRF). The FIB table must be created using "ip6 table add" already. To display the current IPv6 FIB table, use the command show ip6 fib. FIB table will only be displayed if a route has been added to the table, or an IP Address is assigned to an interface in the table (which adds a route automatically).

@note IP addresses added after setting the interface IP table are added to the indicated FIB table. If an IP address is added prior to changing the table then this is an error. The control plane must remove these addresses first and then change the table. VPP will not automatically move the addresses from the old to the new table as it does not know the validity of such a change.

set ioam rewrite

set ioam [trace] [pot] [seqno] [analyse]

This command is used to enable In-band OAM (iOAM) features on IPv6. trace is used to enable iOAM trace feature. pot is used to enable the Proof Of Transit feature. ppc is used to indicate the Per Packet Counter feature for Edge to Edge processing. ppc is used to indicate if this node is an encap node (iOAM edge node where packet enters iOAM domain), a decap node (iOAM edge node where packet leaves iOAM domain) or none (iOAM node where packet is in-transit through the iOAM domain). ppc can only be set if trace or pot is enabled.

Use clear ioam rewrite to disable all features enabled by this command. Use show ioam summary to verify the configured settings.

Example of how to enable trace and pot with ppc set to encap:

set ioam rewrite trace pot ppc encap
