  • Question for WAN admins

    I recently took over ordering T1's for a company and have received the ip address information in various ways. Recently I received the following from Level 3, and am wondering if I am reading this right

    Code:
    IP Version:  	IPv4 
    Edge Device/Port: 	edge1.phx1 - t1-2/1/0:2:9
    Upstream Device/Port:  	Facility ID : 258/T3/PHNDAZ91/PHNDAZ91 
    Vlan: 	
    WAN Network:  	4.31.xxx.88/30 level3 wan .89 customer wan .90 -+- 
    Cust. LAN IPs:  	4.31.xxx.192/29 Route -+-
    Given the above, would I address my wan interface as such:

    ip: 4.31.xxx.90
    sub. 255.255.255.252
    gway 4.31.xxx.88

    Thanks for any replies...

    That would be correct.

      Wouldn't it be this

      Cust. LAN IPs: 4.31.xxx.192/29 Route -+-

      For me that would be the external WAN interface for your edge router.

        The information clearly states "customer LAN IPs", and indicates that this is a routed subnet.

        It also says "WAN network: 4.31.xxx.88/30", and even specifies .89 as "level 3 WAN" and .90 as "customer WAN".

        To the OP: I missed an error in your post. The gateway address should be .89, not .88.

          Ok. laid out differently than I'm used to seeing.

          OP what are the customer LAN IP's for? Is this your private network or you block of IP's from the ISP?

            If you manage your own WAN routers that's usually how you receive the info from the ISP.

              We don't manage ours so typically don't receive them like that.
