VPN-instance view
Parameter
integer: The Maximum routes allowed for a VPN-instance, ranging from 1 to 65536.
alarm-integer: Route threshold for alarming.
syslog-alert: When the route maximum specified for a VPN-instance exceeds the
threshold, routes can be added and only a SYSLOG error message is sent out.
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.
[Quidway] ip vpn-instance vpn1
[Quidway-vpn-vpn1] route-distinguisher 100:1
[Quidway-vpn-vpn1] vpn-target 100:1 import-extcommunity
