[c-nsp] Advice: Which routers to purchase ?

[Dovid Bender]

Jeferson,

1) I do not know much about Cisco. I assumed that if one router failed then the second one would do the BGP.

2) We have an AS and I was told that we would need to BGP to advertise our IP's. We also need to do it so we are ISP independent and can decide who to work with.

3) What other information would you need ? Like I said I am a bit of n00b here.

Regards,

Dovid

  Hi,

  BGP can load-balance but doesnt not scale/converge well and fast as a strong IGP such as OSPF.

  What is the need to run BGP ? ask yourself? Are you becoming an AS or is just because you've heard people set up multihome using BGP?

  If this is not the case, you can always conference the 3 ISP together and ask them to set up OSPF as a PE-CE routing between you and them, that would scale and converge really WELL.

  If that's not the case here, then we would have to go down to BGP design level where much more considerations has to be noted.

  Rgs,

    Hi All,

    I am new to Cisco (other than starting a CCNA course 10 years ago but never finishing it).

    Our company is now becoming multi homed and we need to BGP our own IP's.

    We need at least three Ethernet connections. We will be connecting to two providers and then a third for our network. The physical connection will be 100 mbits to the carriers and 1000 mbit to our switch. From the first carrier we can use 100 mbits and from the second carrier we will only be using up to 5-10 mbits. Our total bandwidth usage will most likely be under 100 mbits. We would also like to use VPN but it's not a must. We are running a VoIP network. I do not know if this is possible but we would like to be able to assign more than one IP per interface. Is that possible ? Also we would like to have two routers for redundancy. We will have a primary and a standby. We would like to use MPLS.

    What do you recommend ?

    Regards,

    Dovid
