There was a problem hiding this comment. @kornoa you implemented this 9 months ago. If we implement this change, we will no add this extra line, but as I see it, the config would actually be more correct with this change. Do you have a running network using the rfc5549 + the There was a problem hiding this comment. Sorry, the customer's project had finished. I don't have access to this implementation anymore.

This is true, but if the neighbor is is a member of the UNDERLAY_PEERS group (which l3_edge does) then line 252 forces the advertisements to advertise with ipv6 next-hops instead. Or at least this was my experience in my testing. Hence the need for the suggested 253. |

There was a problem hiding this comment. @nathanmusser I think we need to keep this neighbor with the next-hop, since we have ipv6_enable. Now I understand why you asked about this a long time ago :-/ |
