Exchanging routing information by using EBGP
In this way, EBGP, IGP, or static routes can be used between the Spoke-PE and the Spoke-
CE.
NOTE
To set up the EBGP peer relation between the Hub-PE and the Hub-CE, run the peer ip-address
allow-as-loop [ number ] command in the BGP VPN instance view to allow the routing loop.
Exchanging routing information by using IGP
In this way, only IGP or static routes can be used between the Spoke-PE and the Spoke-
CE.
Exchanging routing information by using a static route
In this way, EBGP, IGP, or static routes can be used between the Spoke-PE and the Spoke-
CE.
If the Hub-CE uses the default route to access the Hub-PE, to advertise the default route to
all the Spoke-PEs, do as follows on the Hub-PE:
Run the ip route-static vpn-instance vpn-instance-name 0.0.0.0 0.0.0.0 nexthop-
–
address [ tag tag ] [ description text ] command in the system view.
vpn-instance-name refers to the VPN-out; nexthop-address is the IP address of the Hub-
CE interface that is connected with the PE interface bound with the VPN-out.
Run the network 0.0.0.0 0 command in the BGP VPN instance view to advertise the
–
default route to all the Spoke-PEs through MP-BGP.
vpn-instance-name refers to the VPN-out.
