Is it possible to tag routes (via an IGP or BGP) and then perform
a policy route decision which in part does a check for this tag?
Specifically, the logic I'm looking for is a route-map which is
applied in the packet forwarding phase which will change the forwarding
behavior if the packet is for a destination which is covered by
a route advertisement which has one of these special tags.
Pseudo-logic for route-map:
route-map permit 10
if (dst IP is covered by most specific route adverstisement which
has a tag = XYZ) then
set attribute=value
etc.
Extra credit for details on how this can be done on a Juniper or other
platform.
Thanks
