Hi all, I hope someone can help me out...
I understand the concept of eigrp variance, but where do you start in configuration?
Setup: 3 routers. R4 connects to R5 via ethernet, R1 connects to both R4 and R5 via frame-relay.
The task wants R4 to have a load share of 4:1 towards R5.
On my Router 4, here is the topology to my destination:
R4#sho ip eig top 222.22.2.0
IP-EIGRP (AS 1024): Topology entry for 222.22.2.0/24
State is Passive, Query origin flag is 1, 1 Successor(s), FD is 256256
Routing Descriptor Blocks:
174.1.45.5 (Ethernet0/1), from 174.1.45.5, Send flag is 0x0
Composite metric is (256256/256000), Route is External
Vector metric:
Minimum bandwidth is 10000 Kbit
Total delay is 10 microseconds
<snip>
174.1.145.1 (Serial0/0), from 174.1.145.1, Send flag is 0x0
Composite metric is (2170112/1658112), Route is External
Vector metric:
Minimum bandwidth is 1544 Kbit
Total delay is 20010 microseconds
Reliability is 255/255
My metric towards R5 is 256256. So I assume I need a metric towards R5 to be less than 4x 256256?
How do I go about figuring that out? Do I just start randomly picking delay values?
In the solutions guide, they used "delay 21500" for serial 0/0 and "delay 6000" for ethernet0/1.
Where did those numbers come from?
Or am I missing something simple?
In case you're interested, this is from IEWB Lab 8 - Task 3.7
thanks!
