Just another Cisco blog. Follow me on Twitter. Laquo; Nexus Configuration Syncronization. Here’s an example:. N5k-1(config)# port-profile type ethernet VM n5k-1(config-port-prof)# switchport access vlan 225 n5k-1(config-port-prof)# spanning-tree port type edge n5k-1(config-port-prof)# spanning-tree bpduguard enable n5k-1(config-port-prof)# state enabled. Here is how we assign the config to a group of ports:. N5k-1(config)# int e1/22 - 25 n5k-1(config-if-range)# inherit port-profile VM. N5k-1(config-port-...

Using interface bandwidth to influence EIGRP routing decisions. MP-BGP for IPv6 →. IP SLA and Object Tracking. July 15, 2011. I’ve recently been doing some work with our HSRP setup around our network. Like most people, we use HSRP as a first hop redundancy mechanism to provide clients attached to the network with a virtual default gateway. HSRP will, be default, fail from Active to Standby, should the routers lose the ability to talk to one another on the subnet the HSRP for. IP SLA is Internet Protocol ...

November 17, 2011. Today is my penultimate day with my current company; I am moving on to bigger and (hopefully! It’s a weird feeling leaving a job, especially one where you have made so many changes. There is only a small network here ( 700 users, 200 servers) but when I started it had been badly neglected for several years There wasn’t really anyone with sufficient experience to manage a network, so things had just been left and fingers crossed that nothing would go wrong…. Redundant Links were non-exi...

MP-BGP for IPv6 | Link-State
https://linkstate.wordpress.com/2011/08/16/mp-bgp-for-ipv6
IP SLA and Object Tracking. Moving On… →. August 16, 2011. I recently passed the CCNP SWITCH exam, so now Spanning-tree is out the window, and I am firmly concentrated on all things layer 3 in preparation for the CCNP ROUTE exam. One of the areas I have not really had much exposure too is IPv6. So I have spent the last few days going over the theory behind it, and trying to put it into practice. Below is the topology i have been using for MP-BGP (MultiProtocol BGP). Ipv6 address 2001:1: /127. Bgp router-...

Just another Cisco blog. Follow me on Twitter. Laquo; ASA Bridge Groups. I had an interesting conversation the other day regarding OSPF. I don’t want to give too much away, so here we go. This is the topology:. Assume interfaces have correct bandwidth statements and no cost commands have been added. R1 and R2 are redistributing the 192.168.1.0/24 prefix as E2 with a cost of 100. Which path does R4 take to the 192.168.1.0/24 network? Does it load balance? I started a thread on Networking-Forum. Without gi...
