Redistribute routes
Add routes from other routing instances or protocols to the BGP process. You can include OSPF, static, or directly connected
routes in the BGP process with the redistribute command.
● Include directly connected or user-configured (static) routes in ROUTER-BGP-AF mode.
redistribute {connected | static}
● Include specific OSPF routes in IS-IS in ROUTER-BGP-AF mode (1 to 65535).
redistribute ospf process-id
Disable redistributed routes
OS10(conf-router-bgp-af)# no redistribute ospf route-map ospf-to-bgp
Redistribute routes - Example
OS10(config)# router bgp 102
OS10(config-router-bgp-102)# address-family ipv4 unicast
OS10(configure-router-bgpv4-af)# redistribute ospf 12
Additional paths
The add-path command is disabled by default.
1. Assign an AS number in CONFIGURATION mode.
router bgp as-number
2. Enter a neighbor and IP address (A.B.C.D) in ROUTER-BGP mode.
