To verify the presence of VPN routes on a PE (Provider Edge) device in Juniper, the operational mode command "show route table bgp.l3vpn.0" can be used.
Explanation of the answer options:
A. show route table bgp.l3vpn.0: This command displays the routes learned through BGP for the Layer 3 VPN (L3 VPN) network. The 'bgp.l3vpn.0' part of the command refers to the routing table for the BGP-based L3 VPN. This command provides a detailed view of the VPN routes.
B. show route protocol bgp terse | count: This command counts the number of routes learned through BGP (Border Gateway Protocol) in a summary format. However, it does not specifically indicate the presence of VPN routes.
C. show route table inet.0: This command displays the IPv4 unicast routes learned by the device. However, it does not provide information about VPN routes specifically.
D. show route route-type vpn: This command displays the routes with VPN route type. However, it does not provide the complete view of the VPN routes learned via BGP.
Therefore, the correct option to verify the presence of VPN routes on a PE device in Juniper is A. show route table bgp.l3vpn.0.
