|
How often are Hello packets sent out for EIGRP? Select two
|
For (T1 or slower) NBMA networks, hello packets are sent every 60 seconds.
For networks faster than NBMA, hello packets are sent every 5 seconds |

|
When you compared OSPF to Rip v1 and v2 why is it the preferred IGP?
|
Because it is scalable
