NEW QUESTION # 54
A network administrator working for a private service provider with an employee ID: 4872:46:269 wants to configure timers for the BGP process on their Cisco IOS XE router. Which configuration follows guideline timer recommendations and is a valid BGP timer deployment?
- A. router bgp 1.0
bgp router-id 1.1.1.1
no bgp default ipv4-unicast
bgp fast-external-fallover
timers keep-alive 40
timers hold 60 - B. router bgp 1.0
bgp router-id 1.1.1.1
no bgp default Ipv4-unlcast
bgp fast-external-fallover
timers keep-alive 40
timers hold 120 - C. router bgp 1.0
bgp router-id 1.1.1.1
no bgp default ipv4-unicast
bgp fast-external-fallover
timers bgp 40 120 - D. router bgp 1.0
bgp router-id 1.1.1.1
no bgp default ipv4-unicast
bgp fast-external-fallover
timers bgp 40 60
Answer: A
Explanation:
The default BGP timers are:
- Keepalive: 60 seconds
- Holdtime: 180 seconds (3x Keepalive)
For more aggressive convergence, a ratio of 1:3 (Keepalive : Holdtime) is recommended, which ensures efficient BGP session monitoring.
In this case:
- Keepalive = 40 seconds
- Holdtime = 60 seconds
The timers in chosen option follow the 1:3 ratio rule for BGP timer deployment. timers keep-alive
40 and timers hold 60 are valid and well within Cisco IOS XE standards. These values ensure reliable session management while improving convergence performance.
