I am trying to configure Cisco IOS so as to ignore updates received through a particular routing process based on the tag they carry. So far, I found out about the distribute-list command used in router configuration mode, e.g.:
router ospf 100 distribute-list route-map foo in ! route-map foo deny 10 match tag 42 !
The above commands, in my understanding, ignore all routing updates received via OSPF instance 100 carrying a tag with value 42. However, the documentation for IOS release 12.4T says that the route-map clause of the distribute-list command is only available for the OSPF and EIGRP routing protocols.
Do you know of any way to filter updates based on the tag value in routing protocols other than these?
Thanks in advance for your help.
Best regards, Tiago
