Router1 (RPL Owner) Configuration

Toconfigure Router1 (the RPL owne)r:

1. Configurethe interfaces:
[edit]
interfaces{
ge-1/0/1{
vlan-tagging;
encapsulationflexible-ethernet-services;
unit1 {
encapsulationvlan-bridge;
vlan-id100;
}
}
ge-1/2/4{
vlan-tagging;
encapsulationflexible-ethernet-services;
unit1 {
encapsulationvlan-bridge;
vlan-id100;
}
}
}
2. Configurethe bridge domain:
[edit]
bridge-domains{
bd1{
domain-typebridge;
interfacege-1/2/4.1;
interfacege-1/0/1.1;
}
}
3. Configurethe Ethernet ring protection gorup:
[edit]
protocols{
protection-group{
ethernet-ringpg101 {
node-id00:01:01:00:00:01;
ring-protection-link-owner;
