Description

Add MAP domain

Example usage

vpp# map add domain

Declaration and implementation

Declaration: map_add_domain_command (src/vnet/map/map.c line 2176)

Implementation: map_add_domain_command_fn.

map add rule

Summary/usage

map add rule index <domain> psid <psid> ip6-dst <ip6-addr>.

Description

Add MAP rule to a domain

Example usage

vpp# map add rule

Declaration and implementation

Declaration: map_add_rule_command (src/vnet/map/map.c line 2191)

Implementation: map_add_rule_command_fn.

map del domain

Summary/usage

map del domain index <domain>.

Description

Delete MAP domain

Example usage

vpp# map del domain

Declaration and implementation

Declaration: map_del_command (src/vnet/map/map.c line 2204)

Implementation: map_del_domain_command_fn.

map params fragment

Summary/usage

map params fragment inner|outer.

Description

Configure MAP fragmentation behaviour

Example usage

vpp# map params fragment

Declaration and implementation

Declaration: map_fragment_command (src/vnet/map/map.c line 2126)

Implementation: map_fragment_command_fn.

map params fragment ignore-df

Summary/usage

map params fragment ignore-df on|off.

Description

Ignore the IPv4 Don't fragment bit

Example usage

vpp# map params fragment ignore-df

Allows fragmentation of the IPv4 packet even if the DF bit is set. The choice between inner or outer fragmentation of tunnel packets is complicated. The benefit of inner fragmentation is that the ultimate endpoint must reassemble, instead of the tunnel endpoint.

Declaration and implementation

Declaration: map_fragment_df_command (src/vnet/map/map.c line 2145)

Implementation: map_fragment_df_command_fn.

map params icmp source-address

Summary/usage

map params icmp source-address <ip4-address>.

Description

Specifiy the IPv4 source address used for relayed ICMP error messages

Example usage
vpp# map params icmp source-address

This command specifies which IPv4 source address (must be local to the system), that is used for relayed received IPv6 ICMP error messages. 

Declaration and implementation

Declaration: map_icmp_relay_source_address_command (src/vnet/map/map.c line 2097)

Implementation: map_icmp_relay_source_address_command_fn.

map params icmp6 unreachables

Summary/usage

map params icmp6 unreachables {on|off}.

Description

Send IPv6 ICMP unreachables

Example usage
vpp# map params icmp6 unreachables

Send IPv6 ICMP unreachable messages back if security check fails or no MAP domain exists. 

Declaration and implementation

Declaration: map_icmp_unreachables_command (src/vnet/map/map.c line 2113)

Implementation: map_icmp_unreachables_command_fn.

map params pre-resolve

Summary/usage

 map params pre-resolve {ip4-nh <address>} | {ip6-nh <address>}.

Description

Bypass IP4/IP6 lookup

Example usage
vpp# map params pre-resolve

Bypass a second FIB lookup of the translated or encapsulated packet, and forward the packet directly to the specified next-hop. This optimization trades forwarding flexibility for performance. 

Declaration and implementation

Declaration: map_pre_resolve_command (src/vnet/map/map.c line 2062)

Implementation: map_pre_resolve_command_fn.

map params reassembly

Summary/usage

map params reassembly [ip4 | ip6] [lifetime <lifetime-ms>] [pool-size <pool-size>] [buffers <buffers>] [ht-ratio <ht-ratio>].

Description

Configure MAP reassembly behaviour

Example usage
vpp# map params reassembly

Declaration and implementation

Declaration: map_ip4_reass_lifetime_command (src/vnet/map/map.c line 2024)

Implementation: map_params_reass_command_fn.

map params security-check

Summary/usage

map params security-check on|off.

Description

Enable or disable the MAP-E inbound security check

Example usage
vpp# map params security-check

By default, a decapsulated packet's IPv4 source address will be verified against the outer header's IPv6 source address. Disabling this feature will allow IPv4 source address spoofing. 

Declaration and implementation

Declaration: map_security_check_command (src/vnet/map/map.c line 2080)

Implementation: map_security_check_command_fn.

map params security-check fragments

Summary/usage

map params security-check fragments on|off.

Description

Specifiy if the inbound security check should be done on fragments

Example usage
vpp# map params security-check fragments

Typically the inbound on-decapsulation security check is only done on the first packet. The packet that contains the L4 information. While a security check on every fragment is possible, it has a cost. State must be created on the first fragment. 

Declaration and implementation

Declaration: map_security_check_frag_command (src/vnet/map/map.c line 2163)

Implementation: map_security_check_frag_command_fn.

map params traffic-class

Summary/usage

map params traffic-class {0x0-0xff | copy}.

Description

Set or copy the IP TOS/Traffic Class field

Example usage
vpp# map params traffic-class

This command is used to set the traffic-class field in translated or encapsulated packets. If copy is specifed (the default) then the traffic-class/TOS field is copied from the original packet to the translated / encapsulating header. 

Declaration and implementation

Declaration: map_traffic_class_command (src/vnet/map/map.c line 2044)

Implementation: map_traffic_class_command_fn.

Example usage
vpp# show map stats

Declaration and implementation

Declaration: show_map_stats_command (src/vnet/map/map.c line 2230)

Implementation: show_map_stats_command_fn.
