ASR1004 vs ASR9001

[ryan.mchugh]

Greetings,

I am looking at competing engineering bids for upgrading our routing infrastructure.  I have received one proposal that uses the ASR1004(or 1006) and one that uses the ASR9001.  I am having a hard time finding a way to compare feature to feature on these two products and am curious what I'm looking at for pro/cons. 

Scope of project / frame of reference of needs:

We are a small Data Center currently using a pair of 6509-E's with SUP720-3BXL as our core routers.  We presently have a total of 4 Full BGP feeds (split between the 2 6509's) and were looking to grow to 6 total feeds (again split w/ 3 per 6509).  We presently have no IPv6 deployed and would like to start on dual stack as soon as the edge upgrade is completed.  As we are running near 90% memory and hit 100% CPU with our current 4 feeds we know we need to do an upgrade.  At this point a forklift upgrade was ruled out so we were looking to introduce new edge routers to take the heavy BGP work off of hte 6509s.  Our total traffic is tiny compared to the capacity of the 6509s (say 1-2 Gbps aggregate traffic is all) so total throughput is not a big deal for us. 

Any help in comparing feature sets between the 1004 and the 9001 or recomendations would be appreciated.

Ryan, can I reverse the question what features are you in need of today and short/longer term, then I can tell you if the 9001 supports those.

The key difference between the ASR1K and the ASR9K is the operating system, which is IOS-XE for the 1k and XR for the 9k.

IOS-XR has significant benefits such as the ability of SMU's (allowing you to patch the software at run time) and is very powerful and customizable.

The 9001 has 2 hardware forwarders (1 per bay, shared with 2x10G onboard each) and allows for near 100Mpps of total forwarding power. The architecture is the same as his bigger brothers with linecard options (ASR9006, 9010 and the 9922, which also run XR).

If you are interested in the sMU concept or IOS-XR I have some technotes for you on the support forums (that you can find under my profile)

The 9001 has 2 modular bays that allow for 10G, 1G and even 40G interface types.

Sorry for hijack this thread.

Does ASR9K support DMVPN/GETVPN, NBAR, Netflow? And what is different of QoS between 9k and 1k?

[xthuijs]

ASR9k today does not have crypto in the hardware. We are working on that though.

so DMVPN/GETVPN is no. But I can offer you dynamic vpn's with BGP auto dsicovery (not secured though/crypto).

nbar: not in a9k.

QOS: all features are equally supported on both platforms, but QOS is very heavily hardware dependent, so one policy providing the desired implementation on one platfomr, may need tuning on another to achieve the same/similar results.

So functionality equivalent, actual config has differences.

Also there are scale differences in terms of number of queues, policers, buffer space, burst limits, number of classes, pmaps, wred curves things like that.

Look at session 2904 from this years Cisco Live to get a comprehensive overview of the 9k QOS architecture as part of the overal 9K deck I had there.
