Hi all, I have /31s from an upstream provider on v4. If I specify "scope link" in /etc/network/interfaces for these, FRR seemingly doesn't allow the address to be used for update-source. Minimal reproduction example (taken from one of my core routers): /e/n/i config: auto lo iface lo inet loopback up ip addr add 195.246.200.2/32 scope global dev lo auto ens4 iface ens4 inet static address 192.168.1.3/31 scope link FRR config: router bgp 65000 neighbor 192.168.1.2 remote-as 65001 neighbor 192.168.1.2 interface ens4 neighbor 192.168.1.2 update-source 192.168.1.3 What happens in this case, is that FRR sends updates from 172.16.0.2 instead of 192.168.1.3 (despite being explicitly told otherwise!). Have I found a bug, or have I done something stupid? Thanks in advance.
