Found it, I only had to parse the locator TLV from the LSP. |

The name of this json field is incorrect. It should be "endpoint-behavior" or "behavior".

Here, shouldn't be the opposite?
Suggested change

| memcmp(&ls_pref->srv6, &sr, sizeof(struct ls_srv6_sid))) { |
We are comparing the new SID sr that we received from the LSP with the SID we already had ls_pref->srv6.
If memcmp(...) != 0, it means the SID has changed, and therefore we need to update ls_pref->srv6.

According to draft-ietf-lsr-isis-srv6-extensions draft, the End SID should be available in link state prefix information. Add the SID information in the link state prefix, by getting the END SID from the locator TLV information. Signed-off-by: Philippe Guibert <philippe.guibert@6wind.com>
