Cisco Memory for the 26xx and 26xxXM routers

[dbakopanos]

Is there a difference between the two platforms and the memory sticks that are used on them? or are they both interchangagle with?

Hi Dimitri,

The DRAM sticks should be interchangeable. Which exact model are you concerned with?

The 26xx and 26xxXM routers generally have different amounts of memory. I believe that cisco no longer sells memory upgrades for the 26xx.

For the older hardware (especially the 26xx hardware), when memory is an issue some customers look at 12.2(40) since it generally requires a smaller amount of memory for the same feature sets - just realize that the code will be end of engineering next month. I am not recommending you go to this code but sharing another customers solution with you.

well it was for my home CCIE LAB where I didn't have enough memory on one 2611xm to run the 12.4 46 train (I had 90MB  RAM, and the IOS needed 128MB)

last question would be for the CCIE lab as per the Cisco 360 or InterNetworking Experts. I need two backbone routers. now which IOS  feature set wouId need to run the backbone routers?

for INE they say to setup the lab with 2501s, but I have access to a bunch of 2600xm routers which I want to use. how would you convert the BB2 and 3 routers to 26xxXM routers running the same or similar feature sets? (also RAM requirements)

BB1 / Frame Relay Switch	2522	12.2(15)T17	IP Plus	c2500-is-l.122-15.T17.bin
BB2	2501	12.2(15)T17	IP Plus	c2500-is-l.122-15.T17.bin
BB3	2501	12.2(15)T17	IP Plus	c2500-is-l.122-15.T17.bin

Hi Dimitri,

You can go for the 12.3(26) IOS on the 2611XM router. It requires 96 MB of DRAM and 32 MB of flash

I do not think we will lose out on an important feature as 12.2 T train has merged into the 12.3 mainline.

12.3(26) will pretty much have everything what the 12.2(15)T17 has.
