Multihome network and Autonomous System router wth BGP
Posted on 2010-08-27
Am looking for advice on best practices so i can configure a juniper ssg 550M as the main router for a startup ISP.
The upstream provider is operating under the ASN: <hidden> and will advertise there block to us which is x.x.224.0/19 and we will advertise our assigned block (from AFrinic) which is x.x.160.0/22
from the documentation ive been reading, it looks like i will need to use BGP to accomplish this, which in itself seems very simple to setup.
My question is how with the juniper do i then provision segments of our assigned ips to client networks and equipment? The startup was thinking something along the lines of
- /24 - Client network )
- /24 - Wireless network
- /24 NOC-DSL network
which seems simple enough, except if i want some clients modems to get dhcp from the client subnet, and other clients modems to have a block of 4 or 8 static ips that they can configure on their own equipment.
It has been suggested in another forum that i set each client into their own vlan and trunk these to the SSG550. Then assign each vlan their corresponding cidr block and put the default gateway ip on the SSG550. Does this make sense or is it a long shot?
Since this is all new to me, i may be missing some key points. Please let me know if more clarification is required.
