  • 1.  RTR ID in the output show ethernet-switching

    What does RTR ID mean ? 

    Routing instance : default-switch
        Vlan                MAC                 MAC         Age    Logical                NH        RTR
        name                address             flags              interface              Index     ID
        VLAN104             08:05:e2:07:17:7a   D             -   et-0/0/0.0             0         0
        VLAN1100            00:00:5e:00:01:01   DR                esi.1923               0         0
        VLAN1100            08:05:e2:07:17:7a   DR                vtep.32771             0         0

    Not 100% but, I believe it's the same as Active Source, "IP address or Ethernet segment identifier (ESI) of remote entity on which MAC address is learned."

    Mostly used in EVPN, Brisging  VLANs and ISIS.  e.g. 

    user@switch> show ethernet-switching table
    MAC flags (S - static MAC, D - dynamic MAC, L - locally learned, P - Persistent static
               SE - statistics enabled, NM - non configured MAC, R - remote PE MAC, O - ovsdb MAC)
    
    Ethernet switching table : 16 entries, 16 learned Routing instance : default-switch
       Vlan                MAC                 MAC      Logical                SVLBNH/      Active
       name                address             flags    interface              VENH Index   source
       vlanBLACK           00:00:5e:00:53:01   DR       esi.1773               1782         05:00:00:02:9a:00:00:00:68:00 
       vlanBLACK           00:00:5e:00:53:02   DR       esi.1773               1782         05:00:00:02:9a:00:00:00:68:00 
       vlanBLACK           00:00:5e:00:53:80   D        vtep.32772                          10.0.0.1                      
       vlanBLACK           00:00:5e:00:53:00   D        vtep.32769                          10.0.1.1

    thanks so much !!

    Basically I like to know what causes these two different outputs,  platforms ?  configuration ?
    I was trying to locate one MAC, I noticed these two outputs from different switches in EVPN/vXLAN fabrics. I like to know why. 

    Also I opened a case for Juniper Tech support on this.

    The abbreviation is for Router ID.  So I assume this would be an identifier for the routing instance/vpls/evpn  source of the mac address.
