If you use tags to filter the templates, you must apply the same tags to the device to which you want to apply the templates. Otherwise, you get the following error during provisioning: ―Cannot select the device. Not compatible with template.‖

R3 bgp traffic that matched the ACL 100 is dropped and the state is in IDLE

The 10.3.3.3 neighbor goes to IDLE

A label edge router (LER, also known as edge LSR) is a router that operates at the edge of an MPLS network and acts as the entry and exit points for the network. LERs push an MPLS label onto an incoming packet and pop it off an outgoing packet.

Label Switch Router 1. Reads labels and forwards the packet based on the based on the label.

2. Performs PHP

Label Edge Router: 1 Assigns labels and unlabeled packets.

2. Handles traffic between multiple VPNs

From the output, we learned that R1 was trying to establish BGP neighbor relationship with R3 but failed. Both of them were using physical interface to establish neighbor relationship so wedon’t need the “… ebgp-multihop” command here. The only reasonable answer is R3 has not been configured to activate BGP neighbor relationship with R1.
