Hi,

Vlan Rewrite on Mx is handy and can also be done fairly easily. Let see the scenario where it can come into help.

topology

Problem – Service provider has Vlans, which are currently used by customers as well, so technically we cannot have a bridge domain combining our Internal Lan and Customer Lans (speaking purely from the post perspective)

Vlan Rewrite can be used to bypass this issue.

Initially customer tries to ping the SP, but there appears to be no reply from MX.

initial_ping_response_fail

Now, lets configure Bridge domain for these two customers and have Routing-Interfaces associated to individual Bridge-Domains.

configuring_bridge_domains_2

Configuring Vlan-Rewrite

configuring_interface_rewrite

Final verification is much simpler.
