Having troubles with IPv6 and bgp. Traffic comes back on the interface (eth4.431) connected to the bgp peer but traffic won't pass through the kernel to the interface the ping is coming from. Also I can see 4 extra ping replies with tcpdump. Works fine on old Quagga bgpd.
Any ideas what could be going on?
Sanity check more /proc/sys/net/ipv6/conf/*/forwarding and check you have all 1s (TBH, working IPv6 is the main reason to use FRR over Quagga) Tim
