BGP prefix list weird issue

Hello All,

I'm working in a BGP prefix list configuration and i'm seeing a strange issue.

 

Issue: As per the cofiguration we have defined the prefix list to filter the incomming subnets. Though a specific subnet is not allowed in the prefix list but the router is allowing the subnet to get in to BGP table from the neighbour.

 

configuration:

ip prefix-list TEST seq 5 permit 10.61.64.0/19 ge 24 le 24

 

Though the below subnet is not allowed in prefix list but I'm seeing this subnet in BGP table with best path.

 

10.61.192.0/23

 

Can you anybody help me to know what could be the issue? any bug? any thing I'm wrong with the configuration?

 

Thanks,

Thiyagu
