Implementing BGP

Configure Domain Distinguisher

To configure unique identifier four-octet ASN, perform these steps:
SUMMARY STEPS
1. configure
2. router bgp as-number
3. address-family link-state link-state
4. domain-distinguisher unique-id
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 BGP AS number and enters the BGP configuration mode, allowing you to configure the BGP routing
process.
Step 3 address-family link-state link-state
Example:
RP/0/RP0/CPU0:router(config-bgp)# address-family link-state link-state
Enters address-family link-state configuration mode.
Step 4
domain-distinguisher unique-id
Example:
RP/0/RP0/CPU0:router(config-bgp-af)# domain-distinguisher 1234
Configures unique identifier four-octet ASN. Range is from 1 to 4294967295.
Step 5 commit

BGP Permanent Network

BGP permanent network feature supports static routing through BGP. BGP routes to IPv4 or IPv6 destinations
(identified by a route-policy) can be administratively created and selectively advertised to BGP peers. These
routes remain in the routing table until they are administratively removed. A permanent network is used to
define a set of prefixes as permanent, that is, there is only one BGP advertisement or withdrawal in upstream
