[c-nsp] 7600 upgrade recommendations?

[Mack McBride]

I would upgrade the Sup720-3BXLs to RSP720-3CXL with additional ram at the location you are going to take full tables.
If you aren't running 7609S then you would need chassis upgrades which might push you a different direction.

Honestly I would upgrade you border connected routers and leave 7600s at other sites.
I am assuming that you have a single site that actually receives transit.
The ASR1006, should give you good service as a border with ESP40 and SIP40 cards.
The core functionality where you connect to the border routers (I assume you have 2 for redundancy),
Should be capable of doing full tables if you are going to be running full tables.
Honestly you may be better off just accepting customer routes and pruning a lot of the routes out.
Unless your customers are insisting on full tables you could survive quite a while on the 7600 series.

There are really too many ways to skin this to do it without a consultant.

The questions you need to ask are:
1) Do you need full tables (I mean really), if you do then prepare for 9010s.
2) How resilient is your current design (do you need to install redundancy).
3) How many 10G circuits will you be supporting in 18 to 36 months.
4) Do you need full tables everywhere (sites that don't are probably fine with 7600s).

For point four, remember that full table sites cannot transit non-full table sites without
some serious risks unless you use MPLS or some other tunneling protocol so that they never
see the non-full table sites.

Subject: [c-nsp] 7600 upgrade recommendations?

Hi,
I've been a lurker for a long time and just listening and learning but now I'd like some help please.

I'd like some recommendations, we are running a 7609 with dual Sup720-3BXL's and 22 Metro Ethernet connections ranging from 10Mbs up to 10G. We are a service provider for school districts in our county. Our transit traffic is usually 3Gbs ~6Gbs but peaked at 9Gbs yesterday out to our provider.

I have one WS-6708 with two agg circuits (ATT and Comcast) that need to be line rate and also a SIP-400 with a 1x10GE to the provider router which is on site here. I also have one ES-20 (not ES20+) LC with 10 ports active. I still have a channelized DS3 with only 7 DS1's so I can use an 8-port serial if I need to.

I am running BGP with just a default route to our provider but will need to run at least one full table (v4 and v6) in the future. I am running EIGRP to the schools that we provide Internet access for.

ISSUES - We have districts now that are buying point to point 10G circuits and I estimate I will need three 10G ports at line rate (agg circuits) and three that can be oversubscribed in the next year with at least two ports reserve or the ability to add another line card. (So an additional three 10G ports). I need at least ten 1G SFP based ports (I am ready to give up the ES20 and buy the "+" version). I also need shaping, policing and HQoS that doesn't tax the supervisor CPU's. I think the ES20+ LC will do this?

Cisco of course wants to sell me an ASR9K but I am not apposed to staying with the 7600 if it can hang with a few new or used parts....

Thanks in advance!

-Bill
