HAPTER ASIC ONFIGURATION OMMANDS
Description
Using the routing-table limit command, you can limit the route maximum in a
vpn-instance, to avoid too many routes in the ingress interface of the PE router.
Using the undo routing-table limit command, you can remove the limitation.
It is necessary to enter the 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 one of the following formats:
16-bit AS number (ASN): 32-bit user-defined number, e.g., 100:1.
32-bit IP address: 16-bit user-defined number, e.g., 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 input and ingress/egress routing information of the
destination VPN extended community for a router.
Example
[3Com] ip vpn-instance vpn1
[3Com-vpn- vpn1] route-distinguisher 100:1
[3Com-vpn- vpn1] vpn-target 100:1 import-extcommunity

View
OSPF area view
Parameter
source-addr: Source address of sham-link, a loopback interface address with 32-bit
mask
destination-addr: Destination address of sham-link, a loopback interface address
with 32-bit mask
cost-value: Cost at sham link, in the range of 1~65535. By default, it is 1.
password: Specify authentication string in plain text at the interface, 8 characters
at most. It must be consistent with the authentication string of sham link peer.
keyid: Specifies MD5 authentication string at the interface, in range of 1~255
characters. It must be consistent with the authentication string of sham link peer.
key: Specifies authentication string at the interface, 16 characters at most. It must
be consistent with the authentication string of sham link peer. When the display
current-configuration command is executed, the system displays the 24-character
