300-420 Designing Cisco Enterprise Networks (ENSLD)
Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?
- A. Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.
- B. HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.
- C. Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.
- D. Configure BFD between WAN Edge routers to detect sub-second link failures.
