I would like to know how to configure Cisco IOS so as to ignore updates received through a particular routing process based on the tag they carry.
I am aware of 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.
Is there any other way to filter updates based on the tag value in routing protocols other than these?
