  • 1.  l2 interconnect Logical system to main

    Posted 9 days ago

    hello guys i'm trying to have a L2 interconnect from a logical system to main system in mx960 platform.

    what i try to achieve is to have  a bridge domain in LS and irb associated with a specific mac, in main system i need to bridge the irb to a another bridge domain.

    can anyone know the correct way to do this sharing configuration snippet?

    thanks a lot

    G

    You can create a connection between any two isolated virtual sections of the MX using a pair of Logical tunnel interfaces.  These put an interface in each of the two instances that are connected with a virtual link.  On each side you can configure the interface as layer 2 or layer 3 and integrate as needed.

    hello Steve,

    thanks for reply, i want to be more precise, i see the link and i try to connect with encap vlan-bridge or ccc, but lets get to the point:

    i have this on main router:

    domain-type bridge;
    vlan-id 501;
    interface ae2.501;
    interface xe-7/x/x;
    interface xe-4/x/x;
    interface xe-7/x/x;
    interface ae1.xxx;
    interface xe-7/x/x;
    interface ge-9/x/x;
    routing-interface irb.xxx;
    
    set interfaces irb unit xxx family inet sampling input
    set interfaces irb unit xxx family inet sampling output
    set interfaces irb unit xxx family inet address x.x.x.x/24
    set interfaces irb unit xxx family inet6 sampling input
    set interfaces irb unit xxx family inet6 sampling output
    set interfaces irb unit xxx family inet6 address x.x.x.x.x.x.x/64
    set interfaces irb unit xxx mac xx:xx:xx:xx:xx:xx
    
    

    i need to connect the lsys to this bridge with a different administrative mac:

    then i have in lsys:

    set logical-systems xxxxxxx interfaces irb unit xxxxx family inet address x.x.x.x/24
    set logical-systems xxxxxxx interfaces irb unit xxxxx mac xx:xx:xx:xx:xx
    
    set logical-systems xxxxxxx bridge-domains xxxxxxx vlan-id none
    set logical-systems xxxxxxx bridge-domains xxxxxxx routing-interface irb.xxxxx

    the irb interface is different with the main one

    if i try to insert lt interface in respectively bridge-domain the fpc goes at 80% of cpu, and it is not possibile.

    i try to connect with vxlan but no ping i can try with vpls but i want to avoid IGP and LDP if possible.

    please let me know what you think
