Configuration that I need to replace is:
Cisco 1841 (Connected to the internet via ISP (ethernet), Point to point via 2 T1 to another location, backup vpn to another 1841 if PTP fails, Eigrp routing, firewall features, Router on the stick)
Core switch Cisco 2960 (Data, Voice, Mgmt vlans, connected to the rest of the network)
We upgraded ISP to 100Mb/s and it looks like Cisco 1841 can't handle it. I am getting 35 Mb/s download.
What will be best way to replace this? I am thinking to have some decent firewall connected to the internet which will be connected to the core layer 3 switch (for Vlan routing) and then have router connected to the core switch to provide PTP connection and VPN if PTP fails.
Please let me know what do you think, Thank you!
