Limit r1’s FastEthernet0/0 interface to only be able to use up to 3Mbps for EIGRP traffic.
router eigrp 100
network 10.1.12.1 0.0.0.0
ip address 10.1.12.1 255.255.255.0
Routers r1 and INET1 are directly connected via their respective FastEthernet interfaces. Here are their BGP configurations:
r1#show run | sec router bgp
router bgp 65001
timers bgp 15 45
neighbor 126.96.36.199 remote-as 1
INET1#show run | sec router bgp
router bgp 1
neighbor 188.8.131.52 remote-as 65001
Will these two routers establish a BGP peering?
The ‘trick’ to this question was that there is a bgp timers mismatch between the two routers.
keepalive: 60 seconds
holdtime: 180 seconds
r1 is using a keepalive timer of 15 seconds and a hold-time of 45 seconds. INET1 has the default bgp timers of 60 seconds (keepalive) and 180 seconds (hold-time). This is causing a bgp timers mismatch, BUT this will not cause the BGP neighbor relationship to fail:
BGP uses a keepalive timer to define how often that router sends BGP keepalive messages, and a Hold timer to define how long a router will wait without receiving a keepalive message before resetting a neighbor connection. The Open message includes each router’s stated keepalive timer. If they do not match, each router uses the lower of the values for each of the two timers,respectively. Mismatched settings do not prevent the routers from becoming neighbors.
