Referring to the Cisco IOS XR show command output exhibit,
what are three possible reasons that the GigabitEthernet0/1/0/10 LDP IGP sync status is not ready? (Choose three.)
A.
GigabitEthernet0/1/0/10 is not configured to run LDP.
B.
Graceful restart is not configured on the peer.
C.
The LDP neighbor on GigabitEthernet0/1/0/10 is not up.
D.
The OSPF neighbor on GigabitEthernet0/1/0/10 is not up.
E.
LDP is up on GigabitEthernet0/1/0/10, but no label bindings have been received from the peer.
F.
GigabitEthernet0/1/0/10 is a member link of Bundle-Ether9000.

Use the show mpls ldp igp sync command to display MPLS convergence status.
Sync status
MPLS LDP convergence status on a given link.
* Ready – indicates that the link is converged and is ready to be used by IGP.
* Not Ready with Deferred – means that the link fulfills LDP IGP synchronization requirements but is deferred by LDP IGP synchronization delay timeout configuration setting.
* Not Ready – means that the link is not ready to be used by IGP.
Peers
List of peers converged on the given link. If the peer session is GR3-enabled, output is tagged as GR. If GR-only reachability is indicated due to a GR neighbor record recovered from checkpoint after local start, then Chkpt-created flag is also set.
