BGP IPv6

RouterOS Forwarding Protocols
1

Hello,

My ISP provided me 2 ipv6 addresses to establish a BGP session on IPV6:

  • xxxx:8240:127::1 is our neighbour
  • xxxx:8240:127::5 is the ip for our router

So i tried to configure them...
[xxx@yyy] /ipv6 address> print
Flags: X - disabled, I - invalid, D - dynamic, G - global, L - link-local

ADDRESS FROM-POOL INTERFACE ADVERTISE

0 G xxxx:8240:127::5/48 ether01 ... no

Then, when i want to create a new instance in BGP
[TWadmin@RTR DC Rijen] /routing bgp instance> add name=test as=48260 router-id=xxxx:8240:127::5
invalid value for argument router-id

When i try it using Winbox, i get the error "error in router ID - ip address expected". But i do enter an ip address : the xxxx:8240:127::5 ipv6 address from our provider?

Can somebody please explain this?

The BGP router ID is actually a 32 bit integer for both IPv4 and IPv6, so you need to use an IPv4 address, which is a 32 bit integer in dotted quad format.

Best practices suggest that the Router ID to be a valid (single /32) IPv4 Address which is also setup a a Loopback IP on the router.
