set ip next-hop
Sets the next-hop address.
Syntax: [no] set ip next-hop {next-hop|use-peer-address}
next-hop
IP address of the next hop. Packets that match the criteria defined by the match ip next-hop are output to this address.
use-peer-address
IP address of a peer. Next-hop address is set to the peer address on the inbound update routes.
Description: Use the set ip next-hop command to set the value of the next hop attribute in routes that pass the match clauses.
Use the no set ip next-hop command to delete an entry from the route map.
Route maps consist of sets of match and set commands. Match commands define the match criteria for route maps. Routes that match the match criteria are processed according to the actions defined by the set commands. Routes that do not match all of the match criteria in the route map are ignored.
Use the route-map command to create a route map. Use the various match and set commands to define the conditions for redistributing routes between protocols or instances of the same protocol.
The next-hop attribute identifies the next hop to reach a route. Next-hop for an EBGP session is the IP address of the BGP neighbor that announced the route. Next-hop for IBGP sessions is either the BGP neighbor that announced the route (for routes that originate inside the autonomous system) or the BGP neighbor from which the route was learned (for routes injected into the autonomous system via EBGP).
Factory Default: Disabled.
Command Mode: Route map configuration.
Example: In the following example:
- The access-list command creates a standard access list named 20 that allows access for hosts on three specified networks.
- The route-map command creates a route map named nexthop.
- The match ip address command adds a match clause to the route map to match routes permitted by the access list 20.
- The set ip next-hop command specifies that all routes that match the addresses in access list 20 is advertised with a next hop of 10.5.1.190.
router(config)#access-list 20 permit 10.5.1.121 0.0.0.255
router(config)#access-list 20 permit 128.20.0.0 0.0 255.255
router(config)#access-list 20 permit 120.0.0.0 0.255.255.255
router(config)#access-list 20 deny any
router(config)#route-map nexthop permit 10
router(config-route-map)#match ip address 20
router(config-route-map)#set ip next-hop 10.5.1.190
router(config-route-map)#end
router(config)#
