[j-nsp] Multiple lo0 address or how to backup layer2 services

[Rafal Szarecki (WA/EPO)]

Well, let's try this:
 
- do not include lo0 into IS-IS. optionaly configure RID in [edit routing-options] 
- add secondaty IP address on lo0.0. This address will ne l2circuit neighbor.
- write export policy to isis more-or-less like this:
 
term sec-lo {
    from {
        protocol direct;
        route-filter <secondaty lo address>/32 exact;
    }
    then {
        metric xxx
        accept
    }
 
- in ISIS youc should see secondaty address of loopback as external route.
- With this solution you can't use CSPF, because there is no TED info for external router nor secondary lo0 address
