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