Detailed Description

SR policy creation and application.

Create an SR policy. An SR policy can be either of 'default' type or 'spray' type An SR policy has attached a list of SID lists. In case the SR policy is a default one it will load balance among them. An SR policy has associated a BindingSID. In case any packet arrives with IPv6 DA == BindingSID then the SR policy associated to such bindingSID will be applied to such packet.

SR policies can be applied either by using IPv6 encapsulation or SRH insertion. Both methods can be found on this file.

Traffic input usually is IPv6 packets. However it is possible to have IPv4 packets or L2 frames. (that are encapsulated into IPv6 with SRH)

This file provides the appropiates VPP graph nodes to do any of these methods.

Function Documentation

static u8* compute_rewrite_bsid ( ip6_address_t *  sl )

inlinestatic

SR rewrite string computation for SRH insertion with BSID (inline)

Parameters

sl	is a vector of IPv6 addresses composing the Segment List

Returns

precomputed rewrite string for SRH insertion with BSID

Definition at line 241 of file sr_policy_rewrite.c.

Here is the caller graph for this function:

static u8* compute_rewrite_encaps ( ip6_address_t *  sl )

inlinestatic

SR rewrite string computation for IPv6 encapsulation (inline)

Parameters

sl	is a vector of IPv6 addresses composing the Segment List

Returns

Here is the caller graph for this function:

static ip6_sr_sl_t* create_sl ( ip6_sr_policy_t *  sr_policy, ip6_address_t *  sl, u32  weight, u8  is_encap  )

inlinestatic

Creates a Segment List and adds it to an SR policy.

Creates a Segment List and adds it to the SR policy. Notice that the SL are not necessarily unique. Hence there might be two Segment List within the same SR Policy with exactly the same segments and same weight.

Parameters

sr_policy	is the SR policy where the SL will be added
sl	is a vector of IPv6 addresses composing the Segment List
weight	is the weight of the SegmentList (for load-balancing purposes)
is_encap	represents the mode (SRH insertion vs Encapsulation)

Returns

pointer to the just created segment list
