That example was actually taken from a Calix example and modified to 
look more like your example.  Here is a Calix example I took from our 
config file, with the IP munged:

host N42-1-1-4-3-1 {
   host-identifier option agent.remote-id "Ont:N42-1-1-4-3-OntEth1-1";
   fixed-address 192.168.1.200;
}

Note that if you are working with C7s and you are on an older release 
(pre-8, I believe), the Calix-generated option 82 strings are 
null-terminated, so any matches that involve the end of the string must 
take that into consideration.  A "\000" at the end of the match string 
works nicely:

host N42-1-1-4-3-1 {
   host-identifier option agent.remote-id "Ont:N42-1-1-4-3-OntEth1-1\000";
   fixed-address 192.168.1.200;
}
