Re: BGP ADD-PATH capability

by Richard Laager

Sorry for the delay. I owe everyone an update. I did not make any changes. There was still some discussion (albeit not a lot) happening on the bird-users list. Today, I got a reply about this on the IXP Manager mailing list: https://www.inex.ie/pipermail/ixpmanager/2024-January/003739.html Honestly, I'm not sure if this is worth it. I'll just leave this off. Maybe we can revisit in the future if there is more interest and/or if this potential BIRD bug discussion goes somewhere. I reverted my testing changes. -- Richard

Re: BGP ADD-PATH capability

Here is a juniper example set protocols bgp group iBGP-reflector-v4 family inet unicast add-path receive set protocols bgp group iBGP-reflector-v4 family inet unicast add-path send prefix-policy addPathiBGPPolicyASBR set protocols bgp group iBGP-reflector-v4 family inet unicast add-path send path-count 3 addPathiBGPPolicyASBR could be as simple as ‘accept all’ or something more granular. Richard I think addressed this a few weeks back; consider the potential growth of your RIB and recognize that the feature to preinstall the backup path in your FIB, if possible on your hardware, may be a different knob. -Michael From: MICE Discuss <MICE-DISCUSS(a)LISTS.IPHOUSE.NET> On Behalf Of David Farmer Sent: Thursday, January 11, 2024 1:29 PM To: MICE-DISCUSS(a)LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] BGP ADD-PATH capability Here are a couple of Cisco Docs https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bgp/configuration… https://www.cisco.com/c/en/us/support/docs/ip/border-gateway-protocol-bgp/2… Hope that helps; On Thu, Jan 11, 2024 at 11:04 AM Jonathan Stewart <jonathan(a)les.net<mailto:jonathan@les.net>> wrote: Does anyone--like another IX, possibly--have documentation that can be shared about how to enable, disable, or ignore the add-path configuration on the member router?

Re: BGP ADD-PATH capability

Does anyone--like another IX, possibly--have documentation that can be shared about how to enable, disable, or ignore the add-path configuration on the member router? Farmer mentions they didn't have it enabled suggesting each operator would need to enable add-path on their router before the functionality could be used by each member.

I'll add while we are receiving the Additional-Path BGP Capability from RS1, we don't have it enabled on our side, so it is not being negotiated.

Re: BGP ADD-PATH capability

by Richard Laager

I was going to deploy this today. But minutes before I would have tried, someone posted on the bird-users mailing list about add-paths causing sessions with IOS-XR 7.9.2 to shut down. My current plan is to postpone this a week to see if there are any replies on that thread. Unfortunately, I've found the bird mailing lists to be pretty quiet. If nothing changes, then I will attempt this. I was already planning to keep track of which sessions were up before and compare after. Based on what happens, I can revert if needed. It's only one route server, so if someone's session goes down, it's not the end of the world. If you are concerned about this (e.g. you run IOS-XR), another option is that you could pre-emptively disable support for add-paths on your end. -- Richard

MICE Maintenance 2024-01-18 & 2024-01-19

by Richard Laager

Date & Time January 18, 00:00 - 05:00 US/Central January 19, 00:00 - 05:00 US/Central Description Our underlying fiber provider will be doing maintenance on the connection from 511 to Ridgeview. They are attempting to repair some other fiber issues. We may or may not go down. If we did go down, participants on the 511 side would see a loss of BGP to Route Server 2. -- Richard
