Tasks
------------------------------
* R1-R2 256kbps bandwidth link is to have the ability to use 100% of its link for EIGRP messages if needed.
* R1-R2 Configure the necessary variance to allow all 3 links to be used for load balancing.
* R1 Increase the metric of any route within the 192.168.7.0/24 prefix entering the EIGRP route process by 500000.
* R2 No EIGRP AS 1 communications on S0/3.
* R2-R8 Set Hello to 25 seconds and Hold to 80 seconds on R2 S0/3. Set Hello to 10 seconds and Hold to 30 seconds on R8 S0/0.
* R2 S1/0 Summarize 192.168.9.x networks to a /24.
* R2 Mutually redistribute EIGRP AS 1 and EIGRP AS 2.
* R2 Filter prefixes 192.168.6.0/24 and 192.168.7.0/24 outbound on S1/0
* R2-R8-R9 EIGRP AS 2 uses all 5 K values with K1 set at 2 and K2-K5 set as 1.
* R3-R5 MD5 encryption of EIGRP communication. 2 keys are to be used. 1st key is for short time and second key is infinite after first key is done.
* R3 No EIGRP AS 1 communications on S0/1.
* R3 Mutually redistribute between RIPv2 and EIGRP AS 1.
* R5 Enable routes to be advertised out the same interface they came in on for R6 and R7.
* R6 S0/0 Summarize 192.168.6.x networks to a /24.
* R6 Make an EIGRP stub that only advertises summaries.
* R7 Make an EIGRP stub with default advertisements.
* R8-R9 Set Hello to 120 seconds and Hold to 360 seconds on R8 S0/1. Set Hello to 30 seconds and Hold to 90 seconds on R9 S0/0.
* R10 Advertise networks on R11 to rest of network. R11 is EIGRP Stub Receive-Only.
* R10 Mutually redistribute OSPF Area 51 and EIGRP AS 1. Prevent any possible redistribution loops.
* R11 Make and EIGRP stub receive-only.
* R14 Mutually redistribute OSPF Area 51 and EIGRP AS 1. Prevent any possible redistribution loops.
* R15 Advertise only a default route to R17.
* R16 Advertise only a default route to R18.
* R17 Make an EIGRP stub that only advertises connected.
* R18 Make an EIGRP stub that only advertises connected.
* R17&R18 Allow route leak for default routes so if link to upstream router goes down then default will use link R17-R18.

Bloody hell... I haven't had a chance to do the OSPF one yet...

Good work though.

Hi,

@wirerat: Thank you for the effort. I will try to configure this over the weekend (although i am not covered the redistribution topics yet) .

I'll do it, but not this weekend

@wirerat: can we except, step by step configuration guide like for the OSPF lab? I did the EIGRP lab and I want to see your solution (configuration)

Are you using Dynamips or do you have 18 routers?

Hi,

I am using Dynamips/GNS3.

Maybe someday I will get around to the blog. Attached are my config files though.

I was recreating your topology and this is honestly the only thing that I didn't quite get.

If all 3 links from R1 to R2 are set to 256kbps, what is the point of variance? I mean, it will load balance by default, right?

The first item is talking about a specific EIGRP related command that has no effect on actual packets being forwarded by the router.

The second item, in looking at the default configs, one link is set to 256Mbps, one is set to 512Mbps, and the other is not set (default 1.544Mbps). Because of this EIGRP will only use one link and not all three. This is where variance comes into play.

oooohhhhhh... I didn't open up his initial configuration, I was just going to recreate it on the fly... my bad.

Can you elaborate on that first command though? Is he referring to:

Router(config-if)# ip bandwidth-percent eigrp percent ?

Yup, that's the one.

Nice! Will have a crack at this today thank you

Very nice, thanks

thank you for posting this lab
I enjoyed configuring it so much and I look forward to doing the OSPF and BGP ones sometime later.

it was great

Yeah nice one but was there a need for all those routers? Not complaining just commenting.
But all in all a good exercise.
