Implementing BGP
Example:
RP/0/RP0/CPU0:router(config)# route-policy costA
Enters route policy configuration mode and specifies the name of the route policy to be configured.
Step 3 set extcommunity cost { cost-extcommunity-set-name | cost-inline-extcommunity-set } [ additive ]
Example:
RP/0/RP0/CPU0:router(config)# set extcommunity cost cost_A
Specifies the BGP extended community attribute for cost.
Step 4 end-policy
Example:
RP/0/RP0/CPU0:router(config)# end-policy
Ends the definition of a route policy and exits route policy configuration mode.
Step 5 router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 120
Enters BGP configuration mode allowing you to configure the BGP routing process.
Step 6 Do one of the following:
• default-information originate
• aggregate-address address/mask-length [ as-set ] [ as-confed-set ] [ summary-only ] [ route-policy
route-policy-name ]
• redistribute connected [ metric metric-value ] [ route-policy route-policy-name ]
• process-id [ match { external | internal }] [ 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 ]
Applies the cost community to the attach point (route policy).
Step 7
Do one of the following:
• 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 ]
• network { ip-address/prefix-length | ip-address mask } [ route-policy route-policy-name ]
• neighbor ip-address remote-as as-number
