Implementing BGP
SUMMARY STEPS
1. configure
2. router bgp as-number
3. address-family {ipv4|ipv6} {unicast|multicast}
4. maximum-paths ibgp number
5. commit
DETAILED STEPS
Step 1 configure
Step 2
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 100
Specifies the autonomous system number and enters the BGP configuration mode, allowing you to configure the BGP
routing process.
Step 3 address-family {ipv4|ipv6} {unicast|multicast}
Example:
RP/0/RP0/CPU0:router(config-bgp)# address-family ipv4 multicast
Specifies either the IPv4 or IPv6 address family and enters address family configuration submode.
Step 4
maximum-paths ibgp number
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# maximum-paths ibgp 30
Configures the maximum number of iBGP paths for load sharing.
Step 5 commit
iBGP Multipath Loadsharing Configuration: Example
The following is a sample configuration where 30 paths are used for loadsharing:
router bgp 100
address-family ipv4 multicast
maximum-paths ibgp 30
