[dev] Fwd: Problems regarding BGP code 2, sub-code 7 when peering with Cisco IOS-XR Version 4.2.3 over IPv6

Dear Daniel Walton

Is the following intended behavior for FRR ?

1. Type: Multiprotocol extensions capability (1)
   Length: 4
   AFI: IPv4 (1)
   Reserved: 00
   SAFI: Unicast (1)

2. Type: Support for Additional Paths (69)
   Length: 4
   AFI: IPv4 (1)
   SAFI: Unicast (1)
   Send/Receive: Receive (1)

Advertising MP and add-paths 'AFI: IPv4 (1)' instead of 'AFI: IPv6 (2)'

Even through the neighbor-ship is meant to be formed purely over IPv6 ?


Reply from Kelly Cochran <ipv6 at he.net> on a ticket i have with HENET
concerning the ipv6 bgp peering I'm trying to setup with AS6939.

> Unsupported notifications are supposed to send the capability sent which wasn't able to be handled, which in this case is your side sending 01 (type: MP extensions) 04 (length: 4 bytes) 00 02 00 01 (value: AFI: IPv6, SAFI: unicast).  This reads like your side doesn't want to do IPv6 unicast BGP routes

But yes.

All the fuzz is the fault of the Cisco IOS-XR platform not supporting
the add-path capability for eBGP peerings :/

> Add path is not be supported with MDT, tunnel, and L2VPN address families and eBGP peerings.
https://www.cisco.com/c/en/us/td/docs/routers/crs/software/crs_r4-2/routing/configuration/guide/b_routing_cg42crs/b_routing_cg42crs_chapter_01.html

Cisco has only implemented iBGP support for the add-path functionality
(do not know if they have done something different in IOS-XR 6.x releases)

Had the dreary experiencing today (again) when trying to setup a HE
(full feed) BGP tunnel between the pfSense FRR daemon and HE Frankfurt
BGP endpoint.

Refer to attached file. "henetv6-bgp-tunnel-packetcapture.cap"
