Sham-Link - 3Com 8807 Command Reference Manual

754 C 40: BGP/MPLS VPN C C
HAPTER ONFIGURATION OMMANDS
Description
Use the routing-table limit command to limit the route maximum in a
VPN-instance.
Use the undo routing-table limit command to cancel the limitation.
It is necessary to enter a VPN-instance sub-view before using the routing-table
command. Create a VPN-instance routing table in this view and allocate a route
distinguisher (RD) in either of the following formats:
16-bit ASN: A 32-bit user-defined number, for example, 100:1.
32-bit IP address: A 16-bit user-defined number, for example, 172.1.1.1:1.
Create a VPN-target extended community for a VPN-instance and specify ingress
or egress interface or both of them for the vpn-target command. These
parameters can be used to configure ingress/egress routing information of the
VPN-target extended community for a router.
Example
# Configure the maximum routes in VPN instance vpn1 to 1000.
[SW8800] ip vpn-instance vpn1
[3Com-vpn-vpn1] route-distinguisher 100:1
[3Com-vpn-vpn1] vpn-target 100:1 import-extcommunity
