What is causing the BGP session to the 10.1.1.1 neighbor to toggle between the Idle and Active state?
Based on the following show ip bgp neighbor 10.1.1.1 output:
R1#show ip bgp neighbors 10.1.1.1
BGP neighbor is 10.1.1.1, remote AS 65103, external link BGP version 4, remote under ID 0.0.0.0

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?
