DETAILED STEPS
Step 1 configure
Step 2
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120.6
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
Example:
RP/0/RP0/CPU0:router(config-bgp)# address-family ipv4 unicast
Specifies either the IPv4 or IPv6 address family and enters address family configuration submode.
To see a list of all the possible keywords and arguments for this command, use the CLI help (?).
Step 4 table-policy policy-name
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# table-policy tbl-plcy-A
Applies the specified policy to routes being installed into the routing table.
Step 5
commit
Applying routing policy: Example
In the following example, for an eBGP neighbor, if all routes should be accepted and advertised with no
modifications, a simple pass-all policy is configured:
RP/0/RP0/CPU0:router(config)# route-policy pass-all
RP/0/RP0/CPU0:router(config-rpl)# pass
RP/0/RP0/CPU0:router(config-rpl)# end-policy
RP/0/RP0/CPU0:router(config)# commit
