HSRP on both sides of the tunnel?

Question

Cisco

I want to combine 2 offices using a gre-tunnel between cisco routers. In both offices, the provider gives /30, i.e. it is given to me at the first office 1.2.3.6 with the gateway 1.2.3.5, 2.2.3.6 with the gateway 2.2.3.5 in the second. I want to put on both sides 2 881 ciscos, in which the address 1.2.3.6 and 2.2.3.6 is reserved using HSRP. At the first office, I hang addresses on the interfaces: 1.2.3.1, 1.2.3.2, in HSRP I say 1.2.3.6 - common. In the second, respectively: 2.2.3.1, 2.2.3.2, in HSRP 2.2.3.6 - general. With this configuration, cats initiate a connection from an invalid address for the provider 1.2.3.1 (2.2.3.1) and do not see each other, while safely responding to the HSRP address if the request comes from any other host on the Internet.

How can this be overcome?

Answer 1

Well, I will answer myself. The problem was not that the tunnel was not working, but that no traffic was running inside it. everything was decided by replacing ip unnumbered FastEthernet4on ip address 192.168.1.1 255.255.255.252one side, and ip address 192.168.1.2 255.255.255.252on the other
