Juniper Networks 10.4 Example:Configuring Ethernet LFM Between PE and CE

Example:Configuring Ethernet LFM Between PE and CE
Inthis example,LFM is enabled on an IP link between the provider edge(PE) and customer
edge(CE) interfaces. If the link goes down,the fault will be detected by LFM and the
interfaceson both sides will be marked Link-Layer-Down.This results in notifications to
varioussubsystems (for example, routing)which will take appropriate action.
Thelink running LFM is shown in Figure 19 on page 138.
Figure19: Ethernet LFM Between PE and CE
Toconfigure EthernetLFM on an IP link between PE and CE interfaces:
1. ConfigureLFM on the PE router:
[edit]
interfacesge-1/1/0 {
unit0 {
familyinet {
address11.11.11.1/24;
}
}
}
protocols{
oam{
ethernet{
link-fault-management{
interfacege-1/1/0 {
pdu-interval1000;
pdu-threshold5;
}
}
}
}
}
2. ConfigureLFM on the CE router:
[edit]
interfacesge-1/1/0 {
unit0 {
familyinet {
address11.11.11.2/24;
}
}
}
protocols{
oam{
