  • 1.  MultiField CoS for VRF question

    Posted 25 days ago
    I have two PE routers. 

    CE1 <--------> PE1 (VRF1)  <---------> PE2 (VRF2) <------------>  CE2

    If I configured the following line in PE2

    set routing-instances VRF2 forwarding-options family inet filter input vrf.filter

    Which traffic will be filtered by this line ?  Traffic from PE1(VRF1) or traffic from CE2 ?

    thanks a lot in advance !!

    I would *expect* (untested), that it would be either "both", or "only from CE2", depending on whether or not PE2/VRF2 has "vrf-table-label" set.

    With vrf-table-label set, "input" traffic for the VRF is coming from the interface facing CE2 and the lsi interface created by VTL.

    Without vrf-table-label the only interface in the VRF is towards CE2, so the only "input" traffic is from that interface.

    One more question.
    If I need to rate limit some traffic from CE1. Where should I apply MF policy ?

    1. apply it to the interface facing CE
        set interface ge-0/0/0.10 family inet filter input mf.pol

    2.  apply it inside the VRF stanza
         set routing-instances VRF forwarding-options family inet filter input mf.pol

    What are the difference between these two ?

    thanks !!
