Figure 56 AS number substitution configuration (in an IPv4 network)
For example, as shown in
bidirectional communication between the two sites, configure AS number substitution on PE 2 to replace
AS 800 as AS 100 for the BGP route update originated from CE 1 before advertising it to CE 2, and
perform the same configuration on PE 1.
To configure AS number substitution for a peer or peer group (IPv4):
Step
1. Enter system view.
2. Enter BGP view or BGP-VPN
instance view.
3. Configure AS number
substitution for a peer or peer
group.
To configure AS number substitution for a peer or peer group (IPv6):
Step
1. Enter system view.
2. Enter BGP view or BGP-VPN
instance view.
3. Configure AS number
substitution for a peer or peer
group.
Removing private AS numbers from updates sent to an EBGP peer or peer group
Private AS numbers are typically used in test networks, and should not be transmitted in public networks.
The range of private AS numbers is from 64512 to 65535.
To remove private AS numbers from updates sent to an EBGP peer or peer group (IPv4):
Figure 56, CE 1 and CE 2 use the same AS number 800. To implement
