Pass the Juniper JNCIS-SP JN0-363 Questions and answers with ValidTests

When establishing an EBGP session, it's necessary to specify both the local AS number and the local address that the session will use. The local address is required for establishing the TCP connection for BGP. The local AS must be specified to identify the autonomous system of the router.

The show system switchover command is used to display the status of the Graceful Routing Engine Switchover (GRES) feature. This command is available when nonstop routing (NSR) is enabled, which works in conjunction with GRES to maintain uninterrupted routing in case of a Routing Engine switchover.

The exhibit shows the configuration of a virtual switch called sw-1 with two VLANs defined within it: vlan_1 with VLAN ID 1 and vlan_2 with VLAN ID 2. To add interface xe-1/0/5 to the virtual switch, the interface must be associated with one of these VLANs. Since the interface is already configured with vlan-id 2, it implies that it is intended to be part of vlan_2 within the virtual switch sw-1. Therefore, the correct answer is to add interface xe-1/0/5 to the vlan_2 bridge domain under the sw-1 routing instance.

To verify the status of the tunnel from R1, you would issue a ping from the source address that is assigned to R1's end of the tunnel. In the exhibit, we can see that the tunnel interface (gre-0/0/0.0) has the IP address 198.51.100.1 on R1. Therefore, to test the tunnel's status, you should ping the IP address at the other end of the tunnel (which is likely the address on User B's interface or another interface on R2) from R1's tunnel source address.

To influence ISP C to prefer the path through R2 for the 172.20.0.0/16 network, R2 should make its path less preferable to ISP B by prepending its AS number multiple times. This makes the path through R2 appear longer and less desirable to ISP C, which would receive these updates from ISP B. AS path length is a well-known attribute in BGP and is used to determine the best path; paths with a longer AS path are considered less preferable.
