Question

Accepted Answer

BGP is a routing protocol used to exchange routing information between different autonomous systems. It uses path vector algorithm.

Split horizon rule prevents a router from advertising a route back to the same interface from which it was learned.
BGP route reflector is configured by defining a cluster ID and selecting reflector clients.
BGP path selection algorithm selects the best path based on attributes like AS path length, origin code, MED, etc.
EBGP multihop concept is used when the next hop is not directly connected.
OSPF LSA types include router, network, summary, ASBR summary, and external.
OSPF can be redistributed into BGP using the redistribute command.
VRF is a virtual routing and forwarding instance used to isolate traffic between different entities.
RD (route distinguisher) and RT (route target) values are used to uniquely identify VPN routes.
CPU utilization can be checked using commands like show processes cpu or show platform cpu.
