Redistributing Prefixes into Multiprotocol BGP
Perform this task to redistribute prefixes from another protocol into multiprotocol BGP.
Redistribution is the process of injecting prefixes from one routing protocol into another routing
protocol. This task shows how to inject prefixes from another routing protocol into multiprotocol BGP.
Specifically, prefixes that are redistributed into multiprotocol BGP using the redistribute command are
injected into the unicast database, the multicast database, or both.
SUMMARY STEPS
1. configure
2. router bgp autonomous-system-number
3. address-family {ipv4 unicast | ipv4 multicast | ipv6 unicast | ipv6 multicast}
4. redistribute connected [metric metric-value] [route-policy route-policy-name]
or
redistribute isis process-id [level {1 | 1-inter-area | 2}] [metric metric-value] [route-policy
route-policy-name]
or
redistribute ospf process-id [match {external [1 | 2] | internal | nssa-external [1 | 2]]} [metric
metric-value] [route-policy route-policy-name]
or
redistribute ospfv3 process-id [match {external [1 | 2] | internal | nssa-external [1 | 2]]} [metric
metric-value] [route-policy route-policy-name]
or
redistribute static [metric metric-value] [route-policy route-policy-name]

DETAILED STEPS
Command or Action Purpose
Step 1
configure
Example:
RP/0/RP0/CPU0:router# configure
Enters global configuration mode.
Step 2
router bgp
autonomous-system-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Enters BGP configuration mode allowing you to configure
the BGP routing process.
Step 3
address-family {ipv4 unicast | ipv4 multicast |
ipv6 unicast | ipv6 multicast}
Example:
RP/0/RP0/CPU0:router(config-bgp)#
address-family ipv4 unicast
Enters global address family configuration mode for the
IPv4 address family.
