Hi all, Weird one here: In my config I have an eBGP Multihop peer, and for some reason, despite the config looking like this: router bgp 65001 neighbor w.x.y.z remote-as nnnnn neighbor w.x.y.z local-as 205804 neighbor w.x.y.z description Upstream - Peering Router - b neighbor w.x.y.z ebgp-multihop 2 neighbor w.x.y.z disable-connected-check neighbor w.x.y.z update-source 81.187.56.158 address-family ipv4 unicast neighbor w.x.y.z remove-private-AS all replace-AS nnnnn is the correct peer ASN. The resulting PCAP in wireshark shows: Path Attribute - AS_PATH: 205804 65001 Flags: 0x50, Transitive, Extended-Length, Well-known, Complete Type Code: AS_PATH (2) Length: 10 AS Path segment: 205804 65001 Segment type: AS_SEQUENCE (2) Segment length (number of ASN): 2 AS4: 205804 AS4: 65001 I am convinced I have done something wrong, as I expected FRR to strip 65001 from the sequence. I'm running frr 5.0.2 on a pfSense (so alas, upgrading to 6 isn't an option at the moment). Any hints what I've done wrong - or is this a known bug?
