size of nvram in 17xx 26xx and 2691XM routers


I need config in one router 254 Interface Dialers with one ISDN primary and only IOS IP.

For this configuration with 1700 Series seems is sufficient, but I try to use 2621XM and this router is insufficient. The problem not is the processor, the problem is the NVRAM because the length of configuration of the 254 interface dialers is too much large.

The 2621XM router have 32kb. of NVRAM but this memory using SERVICE CONFIG-COMPRES is insufficient if I include descriptions in every dialer.

The 3745 router have approximated 125kb. and this is sufficient.

In the 2691XM router the NVRAM I think is stored in Flash memory, but I don’t know what is the maximum length of startup-config file.

My question is.

What is NVRAM size in 2691XM and in 1700 Series Routers?

Thanks in advance

Re: size of nvram in 17xx 26xx and 2691XM routers

Most routers I've worked with will list the NVRAM amount in the output of show version. It's usually after the interface types.

from a 2620:

Processor board ID JAD06170E1H (3632925778)

M860 processor: part number 0, mask 49

Bridging software.

X.25 software, Version 3.0.0.

1 FastEthernet/IEEE 802.3 interface(s)

2 Serial network interface(s)

32K bytes of non-volatile configuration memory.

16384K bytes of processor board System flash (Read/Write)
