MLAG Peers

[gitfoxvm]

Hello, We normally lab Spine and Leaf designing mirror our Prod environment - the one difference is we use normally RE_USE "169.254.0.0/31" on all our leafs, I was . How can I modify AVD, so that instead of using a POOL, it RE_USES the same slash /31 on all my leafs, I tried changing it hear, but it was a no go:

Definition of pool of IPs to be used for MLAG peer-link connectivity

mlag_peer_ipv4_pool: 169.254.1.0/27 ---> i would like to RE_USE 169.254.0.0/31 on ALL my leafs
# iBGP Peering between MLAG peers
mlag_peer_l3_ipv4_pool: 169.254.0.0/27  --->  i would like to RE_USE 169.254.0.0/31 on ALL my leafs

Hi @gitfoxvm

Indeed this is possible. Please take a look at this section of the documentation: https://avd.arista.com/5.2/ansible_collections/arista/avd/roles/eos_designs/docs/input-variables.html#fabric-ip-addressing.

The IP is still taken from the pool, but if you set

fabric_ip_addressing:
  mlag:
    algorithm: same_subnet

you will get what you ask for.

Let us know if this resolves your question.

Thanks
Claus

That did the trick Claus! QQ - is this within a best practices scope? - Thank you again.
