The correct answer is A. vpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color silver interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color gold. On a Cisco SD-WAN vEdge, TLOC colors must be chosen from the predefined set; 'silver' and 'gold' are valid colors that match the exhibit's interface assignments.

Question

Refer to the exhibit. An engineer is performing a proof of concept before migrating to the Cisco Catalyst SD-WAN solution in the data center by configuring the WAN vEdge101 device. Which configuration accomplishes the task?

Options

  • Avpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color silver interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color gold
  • Bvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color public-internet interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color custom1
  • Cvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color mpls interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color metro-ethernet

Why each option

On a Cisco SD-WAN vEdge, TLOC colors must be chosen from the predefined set; 'silver' and 'gold' are valid colors that match the exhibit's interface assignments.

Avpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color silver interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color goldCorrect

The colors 'silver' and 'gold' are valid predefined TLOC transport colors in Cisco SD-WAN vEdge, and assigning each tunnel-interface a unique TLOC group and color correctly identifies each WAN transport circuit in the overlay.

Bvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color public-internet interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color custom1

'public-internet' is a valid color but 'custom1' and 'public-internet' do not match the color labels required by the exhibit for the two interfaces shown.

Cvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color mpls interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color metro-ethernet

'mpls' and 'metro-ethernet' are valid colors but do not correspond to the transport types depicted in the exhibit, making this configuration incorrect for the proof-of-concept scenario.

Dvpn 0 interface ge0/0 ip address 99.0.0.1/30 tunnel-interface encapsulation ipsec group 101 color mpls interface ge0/1 ip address 192.0.0.1/30 tunnel-interface encapsulation ipsec group 102 color green

'green' is not a valid predefined TLOC color on Cisco SD-WAN vEdge devices, so this configuration would be rejected or produce an unexpected transport identity.
