I have created a pdf document with OSPF Lab 1 and 2 containing a detailed lab breakdown. Check it out if want. Any feedback is most welcome.

Task 1
Configure authentication between R3 and R5 (use password: 'CISCO123'). Configure the BGP timers: hello=30 seconds, holdtime=90 on R3 for all its iBGP peers. R3's iBGP sessions should inherit the same password. Do not use 'neighbor <address> password' command in R3 to accomplish your goal. R1 and R2 and R5 can use this command. The configuration stipulates that iBGP current and future policy in R3 should be configured as a template.Solution
