sonic-quagga's Introduction
Quagga is free software that manages various IPv4 and IPv6 routing protocols. Currently Quagga supports BGP4, BGP4+, OSPFv2, OSPFv3, RIPv1, RIPv2, and RIPng as well as very early support for IS-IS. See the file INSTALL.quagga.txt for building and installation instructions. See the file REPORTING-BUGS to report bugs. Quagga is free software. See the file COPYING for copying conditions.

Agentx support
Hi All,
Could anyone please share some insight on how to configure agentx, either on bgpd.conf or under the vtysh?
it seems that agentx is not accepted under the vtysh mode. Also, the bgpd daemon would stop initializing if i put agentx (as per doc) under the bgpd.conf.j2 & zebra.conf.j2.
I have tried anything i know and nothing works.
Please advise.
Thanks
Quagga failed to sync BGP routes into the routing table
It happens when doing the command service quagga restart

Only two next hops become the multipath and are syncd to the routing table and then kernel.
add set ip src6 support in quagga
ignore next_hop attribute when mp_reach_nlri exists
An UPDATE message that carries no NLRI, other than the one encoded in
the MP_REACH_NLRI attribute, SHOULD NOT carry the NEXT_HOP attribute.
If such a message contains the NEXT_HOP attribute, the BGP speaker
that receives the message SHOULD ignore this attribute.
