R211x-HP Flexfabric 11900 TRILL Configuration Guide

TRILL extension port configuration example

Network requirements

As shown in Figure 10, RB1 and RB2 are in a TRILL network. RB1 is connected to a server, and RB2 is

connected to a core device in a routed network. RB2 has an LSU1TGS48SF0 card in slot 3.

RB2 performs TRILL encapsulation and decapsulation, and serves as a gateway to perform Layer 3

forwarding between the TRILL network and the routed network.

Requirement analysis

• Configure extension port FortyGigE 3/0/49 on RB2 to perform TRILL encapsulation and

decapsulation for packets entering and leaving the TRILL network.

• To avoid broadcast storm, assign extension port FortyGigE 3/0/49 to VLAN 100, and assign

extension port FortyGigE 3/0/50 to VLAN 101.

• For FortyGigE 3/0/49 and FortyGigE 3/0/50 to communicate with each other, map VLAN 101 to

VLAN 100 on extension port FortyGigE 3/0/49.

• For communication between the TRILL network and the routed network, configure VLAN-interface

101 as the gateway to perform Layer 3 forwarding.

Configuration procedures

1. Configure RB1:

# Enable TRILL.

<RB1> system-view

[RB1] trill

[RB1-trill] quit

# Configure port Ten-GigabitEthernet 5/0/5 as a trunk port, assign the port to VLAN 100, and

configure VLAN 100 as the PVID of the port.

[RB1] interface ten-gigabitethernet 5/0/5

[RB1-Ten-GigabitEthernet5/0/5] port link-type trunk

[RB1-Ten-GigabitEthernet5/0/5] port trunk permit vlan 100

[RB1-Ten-GigabitEthernet5/0/5] port trunk pvid vlan 100

# Enable TRILL on port Ten-GigabitEthernet 5/0/5, and set the TRILL link type to trunk.
