Redistribute Routes into BGP4

Routes learned through BGP4 can be redistributed into OSPF or IS-IS. You can specify an optional route-map, which is consulted before routes are added to BGP. Management routes are not redistributed.

1. Access global configuration mode.
   

   device# configure terminal

2. Access BGP configuration mode.
   

   device(config)# router bgp

3. Access BGP IPv4 address family unicast configuration mode.
   

   device(config-bgp-router)# address-family ipv4 unicast

4. Redistribute connected routes.
   

   device(config-bgp-ipv4u)# redistribute connected

This example redistributes IS-IS routes with level 1 packets.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# redistribute isis level-1

This example redistributes static routes with a metric of 200.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# redistribute static metric 200

This example redistributes OSPF external type 1 routes with a metric of 200.

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# address-family ipv4 unicast
device(config-bgp-ipv4u)# redistribute ospf match external1 metric 200
