Hi, we are a small ISP with a Cisco-only core at the moment, consisting of two 6500 series and a couple of Cat2960G aggregation switches. We are looking into deploying to a small IX in the area, which is at the same location as two of our upstreams. So we are going to throw a second fiber to the location and put up a small device that can switch GE linerate for the upstreams and route a couple of 100M to/from the IX into the backbone. We have been considering the Cisco ME6524 series but are now looking at the EX4200-24F as well.
Since I don't have much experience with Juniper in general (and with recent devices like the EX especially) I have a few questions I could not find answered in the datasheets. - How is the interoperatibility with Cisco PVSTP+ on L2? I found http://www.juniper.net/us/en/local/pdf/implementation-guides/8010002-en.pdf which briefly mentions VSTP as being basically the same (and thus fully compatible), but then talks in length about how to get standard STP or MSTP interoperating with Cisco. Does VSTP "just work" as it does in Cisco, plug the device in as you want to and every VLAN gets its own tree? - Datasheet says 16k IPv4 routes and 4k IPv6 routes, I assume this is shared space and an IPv6 route just takes four times the resources of an IPv4 route? - Apart from the small FIB, is there any reason why the EX would not be suitable for this application? Basically we run a fully-dualstacked network, OSPFv2/OSPFv3, BGP, some MPLS/L3VPN (but probably not at this location for the time being). I expect at most 30-40 BGP peers with total prefix count safely within the limits of the hardware. Thanks for your answers, Bernhard _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
