[ROS7.11.2] bgp-large-communities not applied for IPv6 routes

RouterOS Forwarding Protocols
1

On ROS7.11.2 I have a routing filter on ingress that should append bgp-communties and bgp-large-communities to all routes learned from peer. However, just bgp-community is appended - bgp-large-community does not get appended. Here’s the filter chain (32bit-ASN 666666 just for demonstration):

append bgp-communities 64666:470;
append bgp-large-communities 666666:6400:70;
accept;

The peering uses AFI IPv6-only. I have another peering with AFI IPv4-only that works just fine with the same filter syntax.

Am I doing anything wrong here?

Hi,

this is exactly how we are doing this also on 7.11.2 and it works on all of our peers. Sometimes sessions need to be disabled and reenabled when changing route filters especially when you add or move an entry in the filter chain.

Thanks for your feedback Dennis!

It seems the performance of ROS7 with full-tables is pretty poor on Tile.. we’re using CCR1072 here with multiple full tables and it’s really no fun. :frowning:

I started a thread on reddit about the various problems we’re experiencing with full-tables on ROS7/CCR1072 - people over there suggest that it’s working better on the ARM-based CCR2216 models.

I’m currently collecting reproducible faults in order to work with MT support.. :confused:
