Specifying The Vpn Label Processing Mode On The Egress Pe; Configuring Bgp As Number Substitution And Soo Attribute - HP FlexNetwork 10500 Series Configuration Manual

Step
4. Enter OSPF area view.
5. Configure a sham link.
Specifying the VPN label processing mode on the
egress PE
An egress PE can process VPN labels in either POPGO or POP mode:
•
POPGO forwarding—Pops the label and forwards the packet out of the output interface
corresponding to the label.
•
POP forwarding—Pops the label and forwards the packet through the FIB table.
To specify the VPN label processing mode on an egress PE:
Step
1. Enter system view.
2. Enter BGP instance view.
3. Specify the VPN label
processing mode as POPGO
forwarding.
Configuring BGP AS number substitution and
SoO attribute
When CEs at different sites have the same AS number, configure the BGP AS number substitution
feature to avoid route loss.
When a PE uses different interfaces to connect different CEs in a site, the BGP AS number
substitution feature 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 feature and the SoO attribute, see
"BGP AS number substitution and SoO
To configure BGP AS number substitution and SoO attribute:
Step
1. Enter system view.
