Abstract
A method for a service router ('SR') implemented in an active-active SR cluster to move logical resources without explicit negotiations between the service routers ('SRs') in the cluster to provide high availability of services is disclosed. In an embodiment, the method comprises: determining, by an active SR of a plurality of SRs implemented in an active-active SR cluster, that a particular SR has failed; and obtaining, by the active SR, a plurality of hash values computed for the particular SR. The plurality of hash values comprises hash values for the active SR. The active SR determines a maximum hash value of the plurality of hash values, and if the maximum hash value corresponds to, and only to, the hash value determined for the active SR, then the active SR configures a port IP address of the particular SR on the active SR.
