Have client with current Cisco 2851 router(s) running AdvIPServices, also have some CISCO2921 router(s) running IPBase with Data License to provide DLSW bridging path for some remote site HP DTC coverage. Time to upgrade the 2851's and would like to use the new ISR4331 routers.
Cannot find what SW package required to support DLSW bridging. Can someone please advise?
