[Forward ported by Cumulus]
Credit
------
A huge amount of credit for this patch goes to Piotr Chytla for
their 'route tags support' patch that was submitted to quagga-dev
in June 2007.
Documentation
-------------
All ipv4 and ipv6 static route commands now have a "tag" option
which allows the user to set a tag between 1 and 65535.
quagga(config)# ip route 1.1.1.1/32 10.1.1.1 tag ?
<1-65535> Tag value
quagga(config)# ip route 1.1.1.1/32 10.1.1.1 tag 40
quagga(config)#
quagga# show ip route 1.1.1.1/32
Routing entry for 1.1.1.1/32
Known via "static", distance 1, metric 0, tag 40, best
* 10.1.1.1, via swp1
quagga#
The route-map parser supports matching on tags and setting tags
!
route-map MATCH_TAG_18 permit 10
match tag 18
!
!
route-map SET_TAG_22 permit 10
set tag 22
!
BGP and OSPF support:
- matching on tags when redistribing routes from the RIB into BGP/OSPF.
- setting tags when redistribing routes from the RIB into BGP/OSPF.
