[j-nsp] static arp with unnumbered-address

[Alexander Arseniev]

Hello,
Firstly, Your example configuration with static /24 routes and 
qualified-NH to IFL does not commit - even after fixing the host portion 
- with error message "subnet routes are not allowed with MAC NH".
Secondly, You could have second static  198.51.100.0/24 resolve via 1st 
/32:
set routing-instances internet routing-options static route 
192.0.2.11/32 qualified-next-hop et-0/0/0.2766
set routing-instances internet routing-options static route 
198.51.100.0/24 next-hop 192.0.2.11 resolve
Thanks
Alex
