ASR9006 STP PVRST loop guard

[a0]

Hi everyone,

I try to prevent a cross link between two ASR9k from becoming the designated port.

spanning-tree pvrst CORE-CROSSLINK
 vlan 500
  priority 28672
 !
 interface Bundle-Ether1
  vlan 500 cost 2
 !
 interface TenGigE0/1/0/2
  vlan 500 cost 4
  guard root
 !
 interface TenGigE0/1/0/3
  vlan 500 cost 4
  guard root
 !
!

How can I configure the interface 'Bundle-Ether1' with a loop guard?

LoopGuard is not available in XR, you could enable UDLD, though.
