[FROG] Tunnel Encap attribute sub-tlv length 48582 exceeds remaining length 28

[Mike Tancsa]

A couple  of my peers started flapping for some reason this morning with
the error messages


Jan  7 09:48:39 bgpd[19828]: Tunnel Encap attribute sub-tlv length 48582

I was running frr 3.0.3 on FreeBSD RELENG11. Any idea what this bug is
or problematic advertisement ? I started a pcap of the bgp sessions, but
havent found anything obvious yet
