Hi All,Have a challenge for you guys and gals. I am trying to working out if the following is possible...In detail, the exmaple below has a pair of ASAs that are cascaded at a remote site, say ASA_LAN and ASA_WAN. Both would be in L3 routed mode (c...
Hi All,I have EIGRP and OSPF rotuer instances running on Cisco IOS (latest ED) in various VRF-lite pools and want to know if any body knows a way of logging (via SysLog maybe) changes occuring to:- Installed Routing Table (RIB)- EIGRP Topology Change...
Hi All,I need some help.I would like to understand the practical application of using root guard and MST (or PVRST+ for that matter) where different MST instances have different nominal root and secondary positions within the network?Explicitly, wher...
Hi People!Just studying and I have a question about MST link costs which I have noticed, whereby devices that only support pre-standard MST seem to exist in a MST domain all of their own...Take the following scenario, all lines are trunks forwarding ...
Hi Guys and Gals,I am trying to understand how L3 EtherChannel load balancing occurs when used between a multilayer switch and an ISR router.Example config:sw1: int range gi0/20-24 desc linked to gi01-4 on router1 no switchport ...

Hi Dylan,Did you get anywhere with mutliple OSPF neighbors over an IPSEC tunnel?Now ASA9.0 supports site to site VPNs and OSPFv2 in multiple contexts, could cascading two contexts work?James.
As a follow on:Can you define an OSPF neighbors without issuing an "ospf network point-to-point non-broadcast" command on the interface on an ASA, ergo have multiple neighbours within a fragmented area 0?
Hi Guys,Thanks for your responses! I am learning here, hence the post.David: I had looked in to the potential for GRE tunnels, but the side-effects could out weight the benifits. The link provided shows how to pass IKEv1 and ISAKMP traffic through ...
