To forward a packet to 10.0.0.0/8, the router perform the following steps:
Step 1. Search the ip routing table for a route to reach the 10.0.0.0/8 network. Step 2. ___________________________ Step 3. Find the connected outgoing interface to reach 172.16.1.2. Step 4. Arp for the 172.16.1.2 MAC address if it is not already in the ARP cache. Step 5. Store the 172.16.1.2 MAC address in the Fast Switching cache for successive packets to
network 10.0.0.0.
What is step 2?
A. Search the BGP table for an IGP route to reach the BGP next-hop 1.1.1.1.
B. Search the BGP table for an IBGP route to reach the BGP next-hop 1.1.1.1.
C. Search the IP routing table for an IGBP route to reach the BGP next-hop 1.1.1.1.
D. Search the IP routing table for an IGP route to reach the BGP next-hop of 1.1.1.1.

A. The Weight is 0.
B. The origin code is "i,".
C. The Metric (MED) is 0.
D. The BGP next-hop is not reachable.
Answer: D
