Dear all,
My organisation has two (old) Cisco 2600 series routers deployed in two
remote sites, one 2620 and one 2621. So far these routers have been
performing very well, however we are now looking at substantially
increasing the bandwidth of the WAN links that connect these two remote
sites to the central office. At present these remote sites connect to
the central office via 4Mbps ADSL lines and we will be upgrading these
to 100Mbps (full-duplex) optical fibre links. We are essentially trying
to determine whether these old routers will still be able to handle the
increased traffic load or whether we need to upgrade the routers as
well. The information we have managed to find so far suggests that these
routers would be able to cope if all packet switching is done in CEF.
The set-up in these remote sites is quite simple and we only use
extended IP access lists in order to control access to certain VLANs.
Does anybody know whether these ACLs would cause the traffic to be
punted from CEF to process switching?
Many thanks
Terence
