BGP and ios upgrade question

Mailman List Mirror (Read Only)
1

Hello:

A little customer has a Cisco 1841 router running ios 12.3(8r)T8.
At the end of this mail is a "show version" from the router.

Now, he wants to run BGP.

His current ios version 12.3(8r)T8 does not support BGP.

According to Cisco feature navigator, ios version 12.4(24)T
(c1841-ipbasek9-mz.124-24.T.bin) can run in the 1841 and supports BGP
(note that feature set is IPBASE):
http://tools.cisco.com/ITDIT/CFN/Dispatch?act=feature&imageid=1321931&platformFamily=280&featureSet=448&featureSelected=89&availSoftwares=IOS%20XE&availSoftwares=IOS

12.4(24)T requires 128MB DRAM and 32MB flash

Remote peers will announce ONLY the default route to the 1841

My questions are:

1) It is common that a version with an IPBASE feature set supports BGP
(some docs says that bgp support is included in "SP" services feature
set)?
2) Will ios version 12.4(24)T run OK in the 1841?
I think the response will be YES because Cisco feature navigator says
that it is supported and the router has the DRAM and FLASH needed by
14.4(24)T.
3) Must the customer pay in order to download 12.4(24)T or he can
download if he has a valid Cisco maintenance contract for that router?

FWIW, I have 1760's running 12.4(21a) accepting BGP default routes in my remote offices. They run about 20% cpu normally. They also run eigrp with redistribution. No problems. I think if the 1760 can do it the 1841 shouldn't have a problem.

According to Cisco feature navigator, ios version 12.4(24)T
(c1841-ipbasek9-mz.124-24.T.bin) can run in the 1841 and
supports BGP (note that feature set is IPBASE):

1) It is common that a version with an IPBASE feature set
supports BGP (some docs says that bgp support is included in
"SP" services feature set)?

Moving BGP into the IP Base feature set is a recent change.

2) Will ios version 12.4(24)T run OK in the 1841?
I think the response will be YES because Cisco feature
navigator says that it is supported and the router has the
DRAM and FLASH needed by 14.4(24)T.

Yes. Although I wouldn't necessarily use 12.4(24)T, the latest maintenance
build of 12.4(15)T should be more stable.

2%AE-release-12415t/

3) Must the customer pay in order to download 12.4(24)T or he
can download if he has a valid Cisco maintenance contract for
that router?

It's my understanding that you can download any software of the feature set
you're entitled to use if you have SmartNet.

Hope it helps
