hi all, we have a 3945e router and are about to set it production. In the datasheet it says that : * The Cisco 3900 Series enables deployment in high-speed WAN environments with concurrent services enabled up to 350 Mbps. When we enable QoS, can we expect the performance/throughput to drop? are QoS running in hardware/asic? could not find any good reading on this... regards, Paal

I am labbing my IPv6 network: My network addressed with 2001:DB8::/32 prefix. I have done a splitting so that the 2001:DB8::/33 belongs to site 1 and 2001:DB8:8000::/33 belongs to Site 2. I have a host on site 2 with IPv6 address 2001:DB8:8000:600::100/64 which is reachable within our AS but no from anywhere else on the internet. If I want that host to be reachable from rest of the internet i have two options: 1) on Router1 : --> ipv6 router ospf 65512 --> restribute bgp 65512 2) on Router2 : set default-gw to Router 1 --> ipv6 router ::/0 <router 1 ip address> In my head, none of these options seems to be any good. Any tips?

hi, we have a Cisco 2851 router and bought the following IOS:: System image file is "flash:c2800nm-spservicesk9-mz.124-25d.bin" Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version 12.4(25d), RELEASE SOFTWARE (fc1) I thought this version was supposed to have IPv6 support? TEST(config)#ipv6 unicast-routing ^ % Invalid input detected at '^' marker. TEST(config)# which IOS should we buy? regards, Paal

I am able to ping 172.28.10.2 from R1 and 172.28.10.9 from R2 When I set neighbor 172.28.10.9 ebgp-multihop 1 the BGP State = Idle reset connection with : R1-AS100#clear ip bgp 300 when I set neighbor 172.28.10.9 ebgp-multihop 2 BGP state = Established, up for 00:00:07 I thinks that's because it is 2 hops ? Output of 'show ip bgp sum' is in the new drawing with 'show ip route' http://home.netpower.no/paal/bgp-possible2.jpg additional info: R2-AS300#traceroute 193.214.20.211 source vlan2 Type escape sequence to abort.

thanks for your engagement!

Hi, is it possible for R1-AS100 and R2-AS300 to exchange BGP routing while there is a Router3 in the middle of them with Static routing ? BGP without direct link http://home.netpower.no/paal/bgp-possible.jpg regards, Paal

If you don't use firewall feature, but only NAT, you can do the following to redirect port80(HTTP) from WAN to LAN : int fa0 description WAN ip nat outside ! int fa1 description LAN ip address 192.168.2.1 255.255.255.0 ip nat inside ! ip nat inside source static tcp 192.168.2.2 80 80 extendable

hi, we have a site with to connections in with 2 router for failover. We would like to do a more automatic failover when one of the routers fails. This is what I have come up with so far... http://home.netpower.no/paal/hsrp/hsrp-bgp.jpg HSRP on the LAN, but I'm not sure if BGP is the right thing to use on the WAN(ATM) to our HQ Main Router. I find BGP a bit complex to configure, but it's doable. OSPF is easy to set up in VRF's, but how is BGP to configure in VRFs ? any suggestions or tips ?

hi, and if you want everyone on the LAN say 172.16.1.0/24 to have 50kbps each. Is it just to modify the access list to "permit ip 172.16.1.0 0.0.0.255 any" ?
