MVPN mt- interfaces question

  • 1.  MVPN mt- interfaces question

    Posted 26 days ago

    The provide-tunnel I used is pim-asm

    For each vrf mvpn, a pair of mt- interfaces are automatically created as follows:

    root@PE-1# run show pim interfaces instance demo

Name               Stat Mode IP V State        NbrCnt JoinCnt(sg/*g) DR address
lo0.4              Up   S     4 2 DR,NotCap           0 0/0            10.50.4.4
lsi.1              Up   SD    4 2   P2P,NotCap        0 0/0
mt-0/0/0.1081344   Up   SD    4 2   P2P,NotCap        0 0/0
mt-0/0/0.32768     Up   SD    4 2   P2P,NotCap        0 0/0
pe-0/0/0.32770     Up   S     4 2   P2P,NotCap        0 0/0
lsi.1              Up   SD    6 2   P2P,NotCap        0 0/0

    When a new vrf is added with mvpn, a new pair of mt- interfaces are created. 
    My question is the unit assigned to a vrf might be changed ?

    thanks !!
