Deleting a VFI member

Hi,

we've recently changed the configuration of some services in our network and I got tasked with cleaning up the leftover of old configurations. However, now I have to clean up a member from a VFI and I cannot figure out how to do so. The problem is that I cannot figure how to do it. This is the relevant configuration:

show bridge-domain 1908 Bridge-domain 1908 (3 ports in all) State: UP Mac learning: Enabled Aging-Timer: 300 second(s) Maximum address limit: 64000 Port-channel14 service instance 1908 vfi MI1602_MIH401_1908 neighbor 172.16.128.3 5726 vfi MI1602_MIH401_1908 neighbor 172.16.128.3 5723 

I want to delete the member that has the VC id of 5726. So the first step was to take the vfi out of the bridge domain.

#show l2vpn vfi name MI1602_MIH401_1908 Legend: RT=Route-target, S=Split-horizon, Y=Yes, N=No VFI name: MI1602_MIH401_1908, state: down, type: multipoint, signaling: LDP VPN ID: 1022201906 Local attachment circuits: Pseudo-port interface: pseudowire100184 Interface Peer Address VC ID S pseudowire100186 172.16.128.3 5723 Y pseudowire100185 172.16.128.3 5726 Y 

This is the VFI itself. I want to remove the pseudowire 100185 as I said above but I cannot do so. Writing no pseudowire100185 returns me an error as apparently the range of valid pseudowires is up to 100000. So, I cannot even understand how they've created these in the first place. The router is an ASR 907 running IOS-XE 16.6.5a if that's of any help.

Anyone can help or, can provide a link to some documentation that explains VFI and how they work. I cannot find much infos about these online somehow.

Thank you and have a nice day
