I have a customer and I need to announce for them. They are not Mulithomed so they don't have an AS. Am I over thinking this minor issue?
Here is what I was thinking
router bgp xxxx
*add the subnet here making then apart of my network list
network 1xx.1xx.1xx.0 mask 255.255.255.0
ip route 1xx.1xx.1xx.0 255.255.255.0 Gig0/3
Is there something I am missing?

Hello Gabrielle,
the config part is fine.
the network command will work well because in BGP it looks for the prefix in the IP routing table, instead of processing the IP interfaces of the node as it happens with IGPs.
Hope to help

Hello Gabrielle,
the customer public prefix should be registered with your public ASN to pass consistency checks that someone can perform on the internet.
you can check this on the regional registry (ARIN, RIPE and so on).
if the address block is registered to another ASN belonging to another provider this can cause problems and it should be fixed
Hope to help

The ASN is the customers they were rejected an AS number because they are not multihomed. When I do a WHOIS it is the customer I will be announcing for.
I was more worried about the config part. I have many customers with AS but this is the first without one.
