Re: [nznog] BRAS Options

One expects that BGP is already in place there - why complicate it by having some routes in OSPF and some in BGP, then have to re-arrange things when your network grows? Very common small ISP mistake that can be a PITA to correct when you’re 5 times the size (as everyone hopes to be) and doesn’t buy you anything in the mean time.

I don’t disagree but when you’ve got /32’s coming and going between a few 7301’s as they may be bounced around from LAC’s, OSPF can be the simplest and most effective way to skin the cat and keeps it easy for a small deployment like that.

Don’t do that. Put customer routes in to BGP, use OSPF only to carry your loopbacks and router-router links for iBGP to use. Keep your OSPF small, and your BGP big - it’s what they’re both good at.

(OSPF and ISIS are interchangeable here)

Just running OSPF between them all wouldn’t solve that problem for you and worst case MPLS within a VRF?

The multiple 7301 track was were I had been heading with one in Christchurch and one in Auckland. The problem is that most of our clients are RBI and we have no control over which router they appear on from our connections to Vodafone. That would be OK if we used dynamic IPs but we don't and its way too late to go back from that.

If you're looking at 16k+ subs on a single box, you probably need to start being a little careful but otherwise just make sure you've got a decent RP and you should be right.

If you simply need to shift (say) 10Gbps of traffic with "more than a few thousand" but say less than 16k, then anything in the ASR range with an RP2 and ESP40 will almost certainly be ample.

Another thought, considering you mention the 7301, is to scale out horizontally - it's not clear if you're already doing this. The nice bit about that also is you could have a few 7201s sharing the load 4 ways, which means your IP pool overhead to cater for a box failure is also much less than running only two boxes.

From memory if every customer is in QinQ you won't be able to have more than 8000 on a MX80 series chassis due to interface limits.

Yes we need 10 Gbit, at least 3 ports and I'd rather not be too specific about numbers but more than a few thousand.

Apologies for being a bit of a cheap bugger but you know what its like as an SME, it all comes out of my pocket ;-)

Hi all

The time has come to replace my poor old Cisco 7301 and the quote I got for an ASR1002-HX made my eyes water. Still waiting for a Juniper quote but the general discussion seemed like similar numbers.

Are there any other reliable options out there that don't cost more than my first house?

Cheers
