Can I have both HSRP and GLBP configured on ethernet interfaces between two
routers, with different vitual IP addresses, one for HSRP and one for GLBP?

Thanks!

What are you trying achieve with such a config? Since GLBP and HSRP
have similar functionality, it is not clear when configuring both would
be useful. Also, for hosts on the LAN where you have this pair of
routers, what you configure as the default gateway? Will it be the
HSRP virtual IP address or will it be the GLBP virtual IP address?

Having said that, I think if you configured GLBP and HSRP together,
it would probably work fine together. Just that I see no value in
configuring them at the same time time on the same routers.

well I want to use GLBP load balancing features, but only for certain
hosts, not all network. So I guess I could use HSRP for parts of network
where I do not need LB or cannot/do not want rely on routing LB, but for
some other parts of network I could use GLBP LB possibilities.

OK.

Though I could not see why HSRP and GLBP would not work
correctly if configured simultaneously on the same interface, I
decided to do a quick test on my lab routers. I found that it does
work fine and so you should be fine to run the two together.

I had some basic config like the following for the test -

interface Ethernet0
ip address 192.169.0.3 255.255.255.0
no keepalive
standby 2 ip 192.169.0.254
standby 2 priority 150
standby 2 preempt
glbp 10 ip 192.169.0.253

Everything worked fine before and after a switchover.
