EIGRP - Diffusing Update Algorithm - Stuck-In-Active State
6 important questions on EIGRP - Diffusing Update Algorithm - Stuck-In-Active State
What are common reasons for a router does not respond to a query and become stuck in active? 4
- The neighbor router's CPU is overloaded and the router either cannot respond in time or is even unable to process all incoming packets including the EIGRP packets.
- Quality issues on the link are causing packets to be lost
- Low-bandwidth are congested and packets are being delayed or dropped
- The network topology is excessively large
What is the command to set the active timer?
What happens if the active timer's value is reached in EIGRP? 3
-The neighbor that did no reply will be removed from the neighbor table and their adjencencies torn down.
-The diffusing computation will consider if these neighbors have responded with an infinite metric
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
What can be the answers on a SIA-query? 2
-SIA-reply: Yes I still expect my own neighors to send me the replies I have
asked them for
SIA-reply allows to active timer to be reset
When a SIA-reply is sent, what happens with the active timer?
What is the maximum extension for the diffussing computation when SIA-Queries are used?
