i am a new ISP and i serve a residential/Business broadband network for a small city.
I have 2 buildings where my fiber backbone comes in on opposite sides of the city.
Each site has an Edge router/firewall and core distribution equipment running a GPON solution.
The edge router currently routes into the firewall over an RFC1918 address.
One Edge router has a BGP Peering 10 gig link to zayo heading east
the other edge router has a BGP Peering Zayo 10 gig link heading west and also a single kinber link peering over 2 address using 802.1q to route east and west.
We own a /24 for now. This will grow as we do of course
The questions i have are:
What do you professionals recommend the BGP setup here should be? My first thought was to connect the 2 edge routers over IBGP and have them share all 4 paths out to the net. I just want to verify this is the way to go.
We will eventually be doing BGP peering as a service. As it stands today, we do not take in a full route table but this will change by the end of the summer (hopefully). We default route to our providers.
How do i peer with a customer who is multi homed without transiting internet data that does not belong to that customer?
How do i load balance my traffic between to 2 sites?
What are some good resources you guys have that i can use to become and expert at BGP. I just started getting into BGP in the last year. My skill set is decent on the topic but still lacking to take on this new challenge with complete confidence. i have been eating up what i can but the disconnect for me is when we peer with a customer.
For instance, if the customer owns a /24 and does not want us to originate for them, does that mean we only peer with them and nothing else. I assume we will then filter their connection to make sure only their /24 comes through but do i have to add a static route to my edge for their network?
I greatly appreciate the input. This is my first post here. I dont have enough Network Engineering friends. I need to make some LOL.
