Route Cisco /29 range without loosing IP's

Hi,

I am quite used to the point-to-point IP's used between mikrotik routers so that you do not waste IP's, but since my gateway router is connected to a cisco router what is the best way configure both to route the /29 without loosing any of my public IP addresses?

For example, we have a range assigned by our ISP of 87.164.144.88/29. The Cisco SRP router has an IP address of 87.164.144.89. We have the following IP's available to use.

87.164.144.90 <- This is the Mikrotik Router IP.
87.164.144.91
87.164.144.92
87.164.144.93
87.164.144.94

The problem I am facing is the next smaller netmask only allows for two hosts. Is there any way to do this without having to use NAT or Bridging? I need to be able to run those IP's on queues for QOS on the Mikrotik Router.

A point-to-point ip would have been perfect, but unfortunately Cisco does not support it.

Ask the ISP to route the block to you over a /30
