My install crews need to install unconfigured CPE devices on a worksite’s internal network. This internal network has VLANs running on it (required by the vendor we’re using for .1Q and P). The CPE devices need to obtain an IP address via DHCP so I can use DHCP Options to tell the CPEs to connect to the on-site RB600 TFTP server, download configuration files and firmware updates, and then have Internet connectivity.
My current setup is:
Network: Internet <—> single WAN interface <—> RB600 <—> single LAN interface <—> Network with 3 VLANs (10, 30, 40) on various switching devices <—> unconfigured CPEs in DHCP mode with no VLANs assigned
RB600:
- VLAN 10, 30, and 40 interfaces have been created under the LAN interface.
All VLANs have been added as ports to a Bridge.
DHCP server and its associated IP addresses and networks have been assigned to the Bridge.
When the CPEs first connect they have no VLANs associated with them, but they’re able to get an IP address and the associated DHCP Options from the RB600 for TFTP firmware and config files. Clients computers are also able to connect through the CPEs and obtain an IP addresses.
My problem is: once the config files with VLAN information are loaded into the CPEs, I can no longer contact them via ping or telnet from the router.
I know it’s something simple: what am I doing wrong?
(Also, if this is NOT the correct config for what I’m trying to do, please let me know). Thanks.
