  • 1.  6PE PE egress don't forward ping

    Posted 06-28-2013 21:36

    I can't figure out the problem in my configuration .

     

    CE1 - PE1--MPLS RSVP---PE2--CE2

     

    bidireccional LSPs are correctly stablished but ping ICMPv6  from CE1 to CE2  is stranded in PE2.

     

    PE2 receive correctly with Label 2 explicit Null, but ping is not forwarded to CE2 even destination Ipv6

    is in the routing table inet6.0

     

    Spoiler

    root@JunOS-PE2# show protocols bgp
    traceoptions {
    file bgp-log size 5m files 3;
    flag all;
    }
    group internal-peers {
    type internal;
    local-address 10.200.86.3;
    family inet {
    unicast;
    }
    family inet6 {
    labeled-unicast {
    explicit-null;
    }
    }
    neighbor 10.200.86.5;
    }
    group ipv6-external-peers {
    type external;
    local-address 2001:db8:9000:4200::6;
    neighbor 2001:db8:9000:4200::4 {
    peer-as 65000;
    }
    }

    hi

    u need to configure family inet6 on the core facing interfaces no need for ip addresses to be configured but the family must be configured in order the ipv6-tunneling to operate

     

    let me know if it works

    from CE1   #run ping 2001:db8:9000:4301::2 source 2001:db8:8000:4201::2  , 

     

    icmpv6 reach PE2 with Label 2 explicit null , but it is not forwarded to CE2,

     

     

    root@JunOS-PE2# ...ute table inet6.0 match-prefix 2001:db8:9000:4301::/64

    inet6.0: 6 destinations, 6 routes (6 active, 0 holddown, 0 hidden)
    + = Active Route, - = Last Active, * = Both

    2001:db8:9000:4301::/64
    *[BGP/170] 03:26:43, localpref 100
    AS path: 65000 I
    > to 2001:db8:9000:4200::4 via em2.0
