Configuring Bgp As Number Substitution And Soo Attribute; Displaying And Maintaining Ipv6 Mpls L3Vpn - HP MSR2000 Configuration Manual

Configuring BGP AS number substitution and SoO
attribute
When CEs at different sites have the same AS number, configure the BGP AS number substitution function
to avoid route loss.
When a PE uses different interfaces to connect different CEs in a site, the BGP AS number substitution
function introduces a routing loop. To remove the routing loop, configure the SoO attribute on the PE.
For more information about the BGP AS number substitution function and the SoO attribute, see
number substitution and SoO
To configure BGP AS number substitution and SoO attribute:
Step
1. Enter system view.
2. Enter BGP view.
3. Enter BGP-VPN instance view.
4. Enable the BGP AS number
substitution function.
5. Enter BGP-VPN IPv6 unicast
address family view.
6. (Optional.) Configure the SoO
attribute for a BGP peer or
peer group.
For more information about the commands in this section, see Layer 3—IP Routing Command Reference.

Displaying and maintaining IPv6 MPLS L3VPN

You can soft-reset or reset BGP sessions to apply new BGP configurations. A soft reset operation updates
BGP routing information without tearing down BGP connections. A reset operation updates BGP routing
information by tearing down, and then reestablishing BGP connections. Soft reset requires that BGP
peers have route refresh capability.
Use the following commands to soft reset or reset BGP connections:
Task
Manually soft reset BGP sessions
for VPNv6 address family.
Reset BGP sessions for VPNv6
address family.
