Cisco NCS 5500 Series

Example:
RP/0/RP0/CPU0:router(config-bgp)# bgp redistribute-internal
Allows the redistribution of iBGP routes into an IGP, such as IS-IS or OSPF.

Redistribute IGPs to BGP
Perform this task to configure redistribution of a protocol into the VRF address family.
Even if Interior Gateway Protocols (IGPs) are used as the PE-CE protocol, the import logic happens through
BGP. Therefore, all IGP routes have to be imported into the BGP VRF table.
SUMMARY STEPS
1.
configure
2.
router bgp as-number
3.
vrf vrf-name
4.
address-family { ipv4 | ipv6 } unicast
5.
Do one of the following:
•
redistribute connected [ metric metric-value ] [ route-policy route-policy-name ]
•
redistribute isis process-id [ level { 1 | 1-inter-area | 2 }] [ metric metric-value ] [ route-policy
route-policy-name ]
•
redistribute ospf process-id [ match { external [ 1 | 2 ] | internal | nssa-external [ 1 | 2
]}] [ metric metric-value ] [ route-policy route-policy-name ]
•
redistribute ospfv3 process-id [ match { external [ 1 | 2 ] | internal | nssa-external [ 1 |
2 ]}] [ metric metric-value ] [ route-policy route-policy-name ]
•
redistribute rip [ metric metric-value ] [ route-policy route-policy-name ]
•
redistribute static [ metric metric-value ] [ route-policy route-policy-name ]
