Context
Select one of the following configurations as required:
l Configuring EBGP between a PE and a CE
l Configuring IBGP between a PE and a CE
l Configuring the static route between a PE and a CE
l Configuring RIP between a PE and a CE
l Configuring OSPF between a PE and a CE
l Configuring IS-IS between a PE and a CE
Procedure
l Configure EBGP between s PE and a CE.
Perform the following steps on the PE:
1. Run:
system-view
The system view is displayed.
2. Run:
bgp as-number
The BGP view is displayed.
3. Run:
ipv4-family vpn-instance vpn-instance-name
The BGP VPN instance IPv4 address family view is displayed.
4. (Optional) Run:
as-number as-number
An AS number for the VPN instance IPv4 address family is specified.
During network transfer or service identification, a device needs to be simulated as
multiple BGP devices logically. In this case, you can run the as-number command
to configure an AS number for each VPN instance IPv4 address family.
NOTE
The AS number configured in the BGP-VPN instance IPv4 address family view cannot be the
same as the AS number configured in the BGP view.
5. Run:
peer ipv4-address as-number as-number
The CE is specified as the peer of the VPN.
6. (Optional) Run:
peer { ipv4-address | group-name } ebgp-max-hop [ hop-count ]
The maximum number of hops is configured for the EBGP connection.
Generally, one or multiple directly connected physical links exist between EBGP
peers. If the directly connected physical link(s) are not available, run the peer ebgp-
max-hop command to ensure that the TCP connection can be set up between the EBGP
peers through multiple hops.
