rocket_rabbit Posted January 20, 2012 Posted January 20, 2012 Been hammering this the past couple of days ready for 100 people on Monday. Just configuring NSRP on the Junipers now. BT onsite tonight and then a final config of the WAN routers at each end = done Been good getting stuck in again mind! Quote
boris77 Posted January 20, 2012 Posted January 20, 2012 hope you labelled the cables, if its anything like my work over time people add, remove and shift cables leaving it in a right state. even better when they some how wrap fibre round cat 5. Quote
s2k7 Posted January 20, 2012 Posted January 20, 2012 3rd layer switches huh? how many vlans? voice too? careful on spanning tree.... Quote
rocket_rabbit Posted January 20, 2012 Author Posted January 20, 2012 Actually, switches are only layer 2, but stackable. Voice is in there though! I have created a spanning tree loop before, but that was a bit more complex than this and I was tired. boris - no need to label cables this time because they are all short and easily traceable! Quote
s2k7 Posted January 20, 2012 Posted January 20, 2012 (edited) let me know if I can help at the third layer level --- are those POE? ....i'm here to help Westfield honda s2000 & turbo hayabusa lump, F40, Skyline GTR, Esprit V8 & soon FORD GT. http://img195.imageshack.us/img195/513/fordgt.jpg Edited January 20, 2012 by s2k7 Quote
s2rrr Posted January 21, 2012 Posted January 21, 2012 Good stuff ?? where's SteveD when you need him. Maybe the flux capacitor could do with adjustment. Pringles for me please Bob Quote
FILFAN Posted January 21, 2012 Posted January 21, 2012 Oooo now that looks just like my kind of work. Give me a shout if u need a hand. Quote
rocket_rabbit Posted January 21, 2012 Author Posted January 21, 2012 The only thing I will say is that JunOS is awkward. I need to assign an ip to an interface but it needs to be manageable. Menu help only gets you so far though and this is my first foray on juniper CLI. Cisco stuff is easy enough although I have 5 weeks to do another exam or I lose my current quals! Quote
s2k7 Posted January 22, 2012 Posted January 22, 2012 if you will not assign an ip to the interface, no ip route, no default gateway, no router rip, no vlans or trunk your device is only 2nd layer. 3rd layer is the best solution, complex but robust. Capability is enormous. You will build a network second to none. Quote
Blatman Posted January 22, 2012 Posted January 22, 2012 I love spanning-tree! It's one of my favourite protocols. Biggest issue I have is lots of supposed IT engineers don't understand it so switch it off and break loops physically. But that means no redundancy... I always try to add in some Etherchanel links in to my networks so we have faster inter-switch connectivity and good redundancy. Is it a mixed vendor environment at Layer 2? If so then with multiple VLAN's you should use MST to get the VLAN's from the Cisco to the Juniper switches. If it's all Juniper then no worries. It's also no worries if Juniper switches (never used them meself) support PVST like Cisco do. And even then if you have *lots* of VLANS, MST can help cut down on the amount of work the switch fabric has to do. Oh, and NSRP? Some sort of proprietary Standby Routing Protocol for Juniper? Why not use the open standard VRRP? What benefit does NSRP bring over VRRP? Genuine question 'cos I have no idea about NSRP at all... Quote

Capability is enormous. You will build a network second to none. No router RIP? Really? Who uses RIP these days? Yes OK on legacy networks but even then I hope it's RIPv2. EIGRP or OSPF are by far the better choices for an IGP, with EIGRP being the almost certainly the best choice in most cases if you have all Cisco infrastructure. On Cisco switches you need to add the default gateway IP address, even to a Layer 2 switch. Switch(config)#ip default-gateway x.x.x.x Cisco Layer 3 switches are all set for Layer 2 functionality by default. You need to add the command Switch(config)#ip routing to enable Layer 3 routing to work. On a Cisco Layer 3 switch to be able to add an IP address to a physical interface you need to turn off Layer 2 functionality by configuring the interface command Switch(config-if)#no switchport This will allow a physical switch interface to accept Layer 3 commands. I try to avoid this by using SVI's for Layer 3 on a switch, keeping the physical interfaces for Layer 2 functionality wherever possible. Quote
s2k7 Posted January 22, 2012 Posted January 22, 2012 (edited) I assumed the poster is a new to 3rd layer---so router rip v2 is a starting point to learn. Without understanding how routing works, you ain't going no where. Yep, he can use EIGRP/OSPF but a more advance routing protocol. Trouble shooting RIP easier for beginner vs advance EIGRP/OSPF.. I used EIGRP. Edited January 22, 2012 by s2k7 Quote
Blatman Posted January 22, 2012 Posted January 22, 2012 Learning basic RIP/RIPv2 is OK so changes can be made, but it's never going to be chosen as a protocol to use on a new network. So far in my Network career I have never come across a RIP / RIPv2 network. But I can configure and fault find it if I have to. The price goes up though! EIGRP is Cisco propietary of course so it only works on Cisco devices. OSPF is the choice if you have a mixed or non Cisco environment. OSPF can get difficult with multiple area designs especially if we get in to the realms of Stub/Totally Stub and NSSA Areas and Virtual Links, and then we'd be off to the races with re-distribution and route summarisation, which I also love to do!
