All,
I am a little confused about the route-map logic that Cisco use.
In their example from networkers 2000, they say (note the first line in the
table)
that if in your route-map, you have a hit on a permit and set an attribute,
the
route-map will exit?
+--------------------------------------------------------------+
| ROUTE-MAP | MATCH CLAUSE/ | ACCEPT ROUTE and | EXIT |
| STANZA | PREFIX-LIST | SET ATTRIBUTE | ROUTE-MAP |
+-----------+-----------------+--------------------+-----------+
| Permit | Yes/Permit | Yes | Yes |
| | | | |
| Permit | No/Deny | No | No |
| | | | |
| Deny | Yes/Permit | No | Yes |
| | | | |
| Deny | No/Deny | No | No |
+-----------+-----------------+--------------------+-----------+
So I have a route map doing two things for BGP.
1. Setting the next-hop attrib
2. Setting the community
But my route map does not exit after the first hit (permit 10) to set the
next hop.
It does continue to go onto 20 and set my community.
Can someone please clarify this for me.
****Will it always go onto the next route-map statment if there is one? ****
!
ip prefix-list BGP-COMM-LIST seq 5 permit 1.1.1.0/24
ip prefix-list BGP-COMM-LIST seq 10 permit 2.2.2.0/24
!
ip prefix-list BGP-SNH-LIST seq 5 permit 3.3.3.3/32
ip prefix-list BGP-SNH-LIST seq 10 permit 4.4.4.4/32
!
!
route-map BGP-ATTRIB permit 10
match ip address prefix-list BGP-SNH-LIST
set ip next-hop 142.220.10.1
!
route-map BGP-ATTRIB permit 20
match ip address prefix-list BGP-COMM-LIST
set community local-AS
!
route-map BGP-ATTRIB permit 30
