A service provider must deploy 6PE in their network that is enabled for MPLS IPv4 only.
Which Cisco IOS XR template must the engineer use to meet this requirement?
Click on the arrows to vote for the correct answer
A. B. C. D.C.
To enable 6PE in a network that is enabled for MPLS IPv4 only, the engineer must use a specific IOS XR template. Let's examine each of the options provided in the question and see which one is the correct template for this scenario.
A. router bgp 65000 address-family ipv6 unicast allocate-label all neighbor 10.0.0.1 address-family ipv6 labeled-unicast
This template is for BGP peering between two routers that support IPv6. It is not relevant to the scenario described in the question because the network is enabled for MPLS IPv4 only.
B. router bgp 65000 address-family vpnv6 unicast neighbor 10.0.0.1 address-family vpnv6 unicast
This template is for BGP peering between two routers that support VPNv6. It is not relevant to the scenario described in the question because the network is enabled for MPLS IPv4 only.
C. router bgp 65000 address-family ipv4 unicast allocate-label all address-family ipv6 unicast neighbor 10.0.0.1 address-family ipv4 labeled-unicast address-family ipv6 unicast
This template is the correct one for the scenario described in the question. It enables the BGP router to support both IPv4 and IPv6 unicast traffic, allocate labels for both, and advertise labeled IPv4 routes to the IPv6 network.
D. router bgp 65000 address-family vpnv6 unicast allocate-label all neighbor 10.0.0.1 address-family vpnv6 labeled-unicast
This template is for BGP peering between two routers that support VPNv6, similar to option B. It is not relevant to the scenario described in the question because the network is enabled for MPLS IPv4 only.
Therefore, the correct answer is C.
