R2511-HP MSR Router Series Interface Configuration Guide(V5)

2. Configure POS 1/0 on Router B:

# Set the clock mode to master for the interface.

<RouterB> system-view

[RouterB] interface pos 1/0

[RouterB-Pos1/0] clock master

# Assign an IP address to the interface.

[RouterB-Pos1/0] ip address 10.110.1.11 255.255.255.0

# Configure the data link layer protocol and MTU for the interface.

[RouterB-Pos1/0] link-protocol ppp

[RouterB-Pos1/0] mtu 1500

[RouterB-Pos1/0] shutdown

[RouterB-Pos1/0] undo shutdown

Verifying the configuration

# Verify the POS interface settings, for example, on Router A.

<RouterA> display interface pos

# Verify that Router A and Router B can ping each other at the POS interfaces. (Details not shown.)

Connecting routers through POS interfaces across Frame Relay

Network requirements

As shown in Figure 10:

• Routers A, B, and C are DTEs on a Frame Relay network.

• Router A uses Frame Relay sub-interfaces to connect Router B and Router C in different network

segments.

Configuration procedure

1. Configure Router A:

# Set the clock mode to slave on POS interface 1/0.

<RouterA> system-view

[RouterA] interface pos 1/0

[RouterA-Pos1/0] clock slave

# Enable Frame Relay on the interface.
