EIGRP behaviour on different interfaces
Hi,
I have 2 queries…
1. I have some confusion around hello/dead time on different interfaces….Please let me know whether I am correct here…
PPP, HDLC Point-to-Point links > T1 5/15 secs PPP, HDLC Point-to-Point links = 60/180 secs FR Point-to-Point links with speed > T1 5/15 secs FR Point-to-Point links with speed = 60/180 secs FR Multipoint links with speed > T1 5/15 secs FR Multipoint links with speed = 60/180 secs
If the above is true, it means that the hello/dead time depends on bandwidth and not on type of interface.
Am I corrcet ?
2. Two routers are connected in following way….running EIGRP
R1(multipoint, speed T1) —————-FR Cloud————————-(point-to-point, >T1 speed)R2
By default EIGRP would use a hello interval –> 60 secs on R1 –> 5 secs on R2
Though the neighborship would be formed b/w R1 and r2, wudn’t it flap on R2 as the ACK/Hellos received from R1 wud always be after its hold time(15 secs).
Thanks, Sugam
