300-415 Question #290: Real Exam Question with Answer & Explanation
The correct answer is D: vpn 0 interface ge0/6 mtu 1500 vpn 177 ! interface ge0/6.2 ip address 10.2.2.3/24 no shutdown vrrp 2 ipv4 10.2.2.1 track-prefix-list vrrp-prefix-list1 ! interface ge0/6.3 ip address 10.2.3.5/24 no shutdown vrrp 3 ipv4 10.2.3.11 track-prefix-list vrrp-prefix-list1. The configuration correctly applies VRRP to sub-interfaces within VPN 177, providing gateway redundancy for LAN-side devices on WAN Edge router 1, while the main physical interface ge0/6 is placed in VPN 0 for transport.

Explanation
The configuration correctly applies VRRP to sub-interfaces within VPN 177, providing gateway redundancy for LAN-side devices on WAN Edge router 1, while the main physical interface ge0/6 is placed in VPN 0 for transport.
Common mistakes.
- A. This option places the physical interface
ge0/6directly intovpn 177, which is generally incorrect as physical WAN interfaces are typically associated withvpn 0for transport, with service VPNs configured on sub-interfaces. - B. This option is identical to option D and correctly implements the VRRP configuration. Assuming distinct options are intended, D is the designated correct choice.
- C. Similar to option A, this option incorrectly places the physical interface
ge0/6intovpn 177instead ofvpn 0, and also specifies an MTU of 1504 which is less common for a standard Ethernet interface than 1500.
Concept tested. Cisco SD-WAN VRRP configuration
