l Configuring a PIM-SM domain without any RP
Data Preparation
To configure an anycast RP in a PIM-SM domain, you need the following data.
No. Data
1 RP address
2 Interface and address of the local MSDP peer
3 Interface and address of the remote MSDP peer
4 Description of an MSDP peer
7.4.2 Configuring the Interface Address of an RP
Before configuring anycast on the devices in a PIM-SM domain, configure a loopback interface
on each device and assign the same IP address to the loopback interfaces. In addition, advertise
the IP address of the RP through unicast routes to ensure that each device has a reachable route
to the RP interface.
Context
Use a unicast routing protocol in the current network to advertise the address of the newly
configured RP interface. Ensure that all switchs in the network have a route to the RP.
In the PIM-SM domain, do as follows on multiple switchs on which the anycast RP is to be
configured:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface loopback interface-number
The loopback interface view is displayed.
Multiple RPs can use the same IP address in a network. The RPs, therefore, are configured on
the loopback interface.
Step 3 Run:
ip address ip-address { mask | mask-length }
The address of the loopback interface is configured.
The parameters of the command are explained as follows:
l ip-address: specifies the address of an RP. The RPs configured on multiple devices uses the
same IP address.
