Preparing configuration changes for replacement of hardware on CGNAT routers on Junos 21.4R3, the routers contain a line that we cannot type on the router with SPC3 card:

set applications application-set ALG-SET application-set junos-algs-outbound

When we tried to apply the same command on the router with SPC3 card we have the following error:

error: cannot use reserved identifier: junos-algs-outbound

When trying to apply all applications of junos-algs-outbound separately, it works for all but the following 5 application:

application junos-dcerpc-msexchange-directory-rfr;

application junos-dcerpc-msexchange-information-store;

application junos-dcerpc-msexchange-directory-nsp;

application junos-rpc-services-udp;

application junos-rpc-services-tcp;

LAB_mx960# set applications application-set ALG-SET application junos-rpc-services-udp

error: cannot use reserved identifier: junos-rpc-services-udp

# set applications application-set ALG-SET application junos-dcerpc-msexchange-directory-rfr

error: cannot use reserved identifier: junos-dcerpc-msexchange-directory-rfr

Commented applications of junos-algs-outbound are not supported with MX-SPC3. They are likely not needed, but user can define custom applications if needed
