R3 is not forming BGP neighborship with any of the routers within the R2-R3-R7 triangular.
Fix the issue to make the network stable within AS237

NOTE: As soon as the issue resolved, a script will run and generate a vty message which will be sent your line with the details of Ticket3

BGP is flapping between R4 and R5. Due to this issue the network is not in a converged state.
Fix the issue to make the network stable, and get 55.55.55.55/32 installed in R1s RIB properly
NOTE: In some cases, you need to wait up to 90 sec to confirm the correct solution.
A syslog message will be generated on R1,R4 as soon as the problem solved.

R1 Lo0: 11.11.11.11
R5 Lo0: 55.55,.55.55
