Re: MPLS TE PCALC error: destination IP addr not found

Is the "metric-style wide" also configured under ISIS ? Here is an example
from my XR router.

router isis 10
 is-type level-2-only
 net 49.0001.1720.1600.1004.00
 nsf cisco
 address-family ipv4 unicast
  metric-style wide
  mpls traffic-eng level-1-2
  mpls traffic-eng router-id 4.4.4.4
  spf-interval maximum-wait 30000 initial-wait 30000 secondary-wait 30000
  maximum-paths 32
 !
 address-family ipv6 unicast
  metric-style wide
  spf-interval maximum-wait 60000 initial-wait 60000 secondary-wait 60000
  maximum-paths 32
  redistribute connected
