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.

# Configure the maximum routes in VPN instance vpn1 to 1000.

source-addr: Source address of a Sham-link, a Loopback interface address with a 
32-bit mask.

destination-addr: Destination address of a Sham-link, a Loopback interface 
address with a 32-bit mask.

cost-value: Cost at Sham-link, in the range of 1 to 65535. By default, it is 1.

password: Authentication in plain text on the interface, 8 characters at most. It 
must be consistent with the authentication of a Sham-link peer.

keyid: MD5 authentication identifier on the interface. The keyed is in the range of 
1 to 255. It must be consistent with the authentication string of Sham-link peer.
