The correct answer is C. Connect multiple IGP/LDP domains using a BGP IPv4 unicast family on the ABR. E. Transport site routes using a BGP VPNv4 address family on the PE routers. Option C - This is a suitable solution as it enables connecting different IGP domains at the ABR (Area Border Router) level using BGP for inter-domain routing. This provides a scalable solution for managing the growing number of routes and interconnecting bank sites A and B…
Question
Refer to the exhibit. An architect must design a solution to connect bank site A with bank site B and support:
- network operation center monitoring end-to-end L3VPN and L2VPN
traffic
- company adding thousands of routes in the next two years
Which two BGP solutions must the design include? (Choose two.)
Exhibit
Options
- AEstablish full mesh IBGP peering with all routers in different IGP domains.
- BRedistribute different IGP domain routes in a BGP IPv4 routing instance.
- CConnect multiple IGP/LDP domains using a BGP IPv4 unicast family on the ABR.
- DApply BGP policies on all routers to filter out ABR and PE loopback IP addresses.
- ETransport site routes using a BGP VPNv4 address family on the PE routers.

Explanation
Option C - This is a suitable solution as it enables connecting different IGP domains at the ABR (Area Border Router) level using BGP for inter-domain routing. This provides a scalable solution for managing the growing number of routes and interconnecting bank sites A and B. Option E - Transport site routes using a BGP VPNv4 address family on the PE routers - This is a suitable solution as it enables transporting both L3VPN and L2VPN traffic using the BGP VPNv4 address family on the Provider Edge (PE) routers. This provides the necessary support for end- to-end traffic monitoring and scalability as the company adds thousands of routes in the future.
