What is the default hold interval for EIGRP?
EIGRP uses a default Hello timer of 5 seconds and a default Hold timer of 15 on LAN interfaces.
What is EIGRP Hello timer?
The hello timer is the interval at which a router will send “hello” messages to neighboring routers to let them know that the originating router is still online and the hold-down timer is the interval at which to consider a neighbor dead if a hello message is not received during that time window.
How do I change hold time in EIGRP?
Hold timer: The hold time is typically three times the hello interval. You can adjust the hold time with the ip hold-time eigrp command.
How does EIGRP determine delay?
Delay is the total measure of delay in the path, measured in tens of microseconds (μs). The EIGRP formula is based on the IGRP metric formula, except the output is multiplied by 256 to change the metric from 24 bits to 32 bits.
Is OSPF better than EIGRP?
EIGRP vs OSPF: Scalability. The scalability of the OSPF is higher than EIGRP because EIGRP is complicated and vendor-specific and incapable of migrating from one vendor to the other. Conversely, OSPF is an open standard and simple protocol through which the network can be scaled easily.
How often does EIGRP update?
EIGRP sets updates only when necessary and sends them only to neighboring routers. There is no periodic update timer. EIGRP uses hello packets to learn of neighboring routers. On high-speed networks, the default hello packet interval is 5 seconds.
How does EIGRP do load balancing?
Configure Load Balancing on Cisco EIGRP using Unequal Routes
- Examine the current best route to the destination. On the originating router, use command show ip route [destination IP] to show the best route to reach the destination IP.
- Identify EIGRP Feasible Successor (FS) routes.
- Configure the variance value.
What is EIGRP unequal cost load balancing?
EIGRP does equal cost load balancing automatically, where as unequal cost load balancing in not automatic, for unequal cost load balancing we need to enable Variance. EIGRP can load balancing up to six paths, and default is four paths. The maximum numbers of paths are based on Cisco IOS versions and router platform.
What is stuck in active state in EIGRP?
EIGRP is a reliable protocol and for each query a router sends to its neighbors it must get a reply in response within 3 minutes. If the router does not receive a reply to ALL its outstanding queries it will put the route in SIA (Stuck in Active) state and will kill the neighbor adjacency.
