Hi, General feel for the boxes:
ISR4331 is and enterprise/corporate type device. Quite flexible and versatile (albeit at a cost of lower throughput). ASR920 is a carrier MPLS aggregation/edge for mainly L2 services. Non-internet scale of L3 can be done as well. Can only forward packets (with limited ability to manipulate them), can not do any "services" (NAT, IPSEC, netflow, etc) I've used the ISRs for the typical enterprise edge (some NAT, ACLs, DHCP relays etc - i.e. internal facing) deployments and the ASR family - for the L2 MPLS aggregation/access (i.e. external facing). If you think that your deployment requires anything more than plain forwarding of packets - then ISR is the way to go, otherwise - ASR is the better (IMHO) choice. kind regards Pshem On Tue, 22 Sep 2015 at 12:53 Michael Malitsky <malit...@netabn.com> wrote: > I need to upgrade the edge router for one of my deployments.
