To confirm if ipv6 route exists in MX960

Hi I wnat to confirm if the route (2111:4111:4116:f113:4310:250::/126) exist in MX960. I am using the below command and get its output

this one has nothing at all

WWW> show route all | match 2111:4111:4116:f113:4310:250::/126

but after removing /126, i get the below one

WWW> show route all | match 2111:4111:4116:f113:4310:250::
2111:4111:4116:f113:4310:250:: /127

What does that mean? Can I say  2111:4111:4116:f113:4310:250::/126 does not exist, but it has a summary, which is  2111:4111:4116:f113:4310:250::/127 ? Thanks
