Troubleshooting MD VPN
This section describes common MD VPN problems and how to troubleshoot them.
A default-MDT cannot be established
Symptom
The default-MDT cannot be established. PIM neighboring relationship cannot be established
between PE devices' interfaces that are in the same VPN instance.
Solution
To resolve the problem:
1.
Use the
display interface
command to examine the MTI interface state and address
encapsulation on the MTI.
2.
Use the
display multicast-domain default-group
command to verify that the same
default-group address has been configured for the same VPN instance on different PE devices.
3.
Use the
display pim interface
command to verify the following:
PIM is enabled on a minimum of one interface of the same VPN on different PE devices.
The same PIM mode is running on all the interfaces of the same VPN instance on different
PE devices and on all the interfaces of the P router.
4.
Use the
display ip routing-table
command to verify that a unicast route exists from the VPN
instance on the local PE device to the same VPN instance on each remote PE device.
5.
Use the
display bgp peer
command to verify that the BGP peer connections have been
correctly configured.
6.
If the problem persists, contact Hewlett Packard Enterprise Support.
An MVRF cannot be created
Symptom
A VPN instance cannot create an MVRF correctly.
