Filtering
NOTE
This parameter applies only to routes redistributed into OSPF.
NOTE
You also can set the tag value using a table map. The table map changes the value only when the
Layer 3 switch places the route in the IP route table instead of changing the value in the BGP route
table. Refer to
“Using a table map to set the tag value”
The weight num parameter sets the weight for the route. You can specify a weight value from
0 through 4294967295.
Setting a BP4 route MED to the same value as the IGP metric of the next-hop route
To set a route's MED to the same value as the IGP metric of the BGP4 next-hop route, when
advertising the route to a neighbor, enter commands such as the following.
Brocade(config)#access-list 1 permit 192.168.9.0 0.0.0.255
Brocade(config)#route-map bgp4 permit 1
Brocade(config-routemap bgp4)#match ip address 1
Brocade(config-routemap bgp4)#set metric-type internal
The first command configures an ACL that matches on routes with destination network
192.168.9.0. The remaining commands configure a route map that matches on the destination
network in ACL 1, then sets the metric type for those routes to the same value as the IGP metric of
the BGP4 next-hop route.
Syntax: set metric-type internal
Setting the next hop of a BGP4 route
To set the next hop address of a BGP4 route to a neighbor address, enter commands such as the
following.
Brocade(config)#route-map bgp5 permit 1
Brocade(config-routemap bgp5)#match ip address 1
Brocade(config-routemap bgp5)#set ip next-hop peer-address
These commands configure a route map that matches on routes whose destination network is
specified in ACL 1, and sets the next hop in the routes to the neighbor address (inbound filtering) or
the local IP address of the BGP4 session (outbound filtering).
Syntax: set ip next-hop peer-address
The value that the software substitutes for peer-address depends on whether the route map is
used for inbound filtering or outbound filtering:
•
When you use the set ip next-hop peer-address command in an inbound route map filter,
peer-address substitutes for the neighbor IP address.
•
When you use the set ip next-hop peer-address command in an outbound route map filter,
peer-address substitutes for the local IP address of the BGP4 session.
NOTE
You can use this command for a peer group configuration.
