We have two parallel metro Ethernet links into the same VLAN from a critical site, but our provider doesn't support link aggregation/Etherchannel (and they're different speeds anyway), so we only have manual failover so far. Cisco Performance Routing...

Switches learn which ports connect to which MAC addresses, and direct traffic to them accordingly. Is there a routing protocol/config/algorithm which learns which interface connects to a specified subnet by seeing a source IP from that subnet? And ...

In a hub-and-spoke IPSec environment, it's not hard to set up routing from spoke to hub. But on the hub end of a tunnel, where lives the gateway of last resort for traffic from the spoke, it seems almost counter-intuitive that the crypto ACL and peer...

Our 1721 redistributes into our 10.25.x.x WAN via RIP several static routes to hosts in an external 10.15.x.x network. However, there's another host in 10.15 that I need to access via a different gateway on another subnet that's directly connected to...

Will this extend our main site's local subnet to a new MetroE site? (Need sanity check.)The main site is routed to a MetroE multipoint net. The router's MetroE interface emits mostly untagged traffic but also creates a dot1q VLAN 99 dedicated to on...

Fascinating...thank you, Peter. My context (not in the original question!) makes ARP-triggered route changes impractical. The scenario involves failover between alternate WAN paths which terminate in different organizations.After some digging, I'm ...

How do the Avaya phones at the remote locations connect to the 870?

One way is to create an interface for each vlan (they don't exist automatically), and give each interface an IP on the correct subnet. My example: VLAN 2 uses 10.1.2.0/24VLAN 3 uses 10.1.3.0/24ip routinginterface vlan 2 no shutdown ip address 10....

Thanks for the thought. If I use route maps to set next hop, my impression is that the packet would reach the router first and then have its Next Hop changed. Seems it would be more direct if the router tells the other routers (via RIP) where to se...

Agreed, per-vlan STP BPDUs determine forwarding/blocking. But if the switch doesn't have a vlan configured, it will block that vlan regardless of the BPDUs, right?If the switch is on the transit path, it must know about the Vlans between the 2 Edge ...

Anything like performance routing available for L2?

Routing somewhat like switching?

Why no implicit route for L2L IPSec tunnel traffic?

Can RIP v2 announce a "foreign" host-based static route?

Add VLAN to MetroE passthru trunk on 2960?
