Hi everybody, I'm playing with a CGSE servicecard and trying to get an idea how many servicecards I would need to support all our customers. I know that on servicecard can support upto 20M sessions but the problem which I currently face is that if I activate a reporting using the netflow I can't reach anymore this number. Is it expected behaviour or do I something wrong by activating the netflow?  ... View more

Hi, I'm trying to find out how to use a low-end cisco router (2800/1800/800) as a DS-Lite client side. Is it possible? ... View more

Hi, I was reading a lot about different IPv6 transition technologies, but it's most about tunneling or providing an access to IPv4 Internet from  IPv6 only host. What I need is other way around. There is a IPv6 only hosting services, with many services running only IPv6.  Some of these services should visible from IPv4 Internet, they could be a normal Web or Mail server, or some P2P protocols. With a technologies like NAT64 we can easily provide access from those IPV6 server to Internet, but other direction is difficult. The only way  I can see it's a static NAT64 mapping, but as you can imaging in hosting environment it's quite impossible. Assigning servers an additional (private) IPv4 and doing a normal NAT44 is not an option. 1:1 mapping is not very interesting also, we'd like to use a rather small IPv4 pool to share it between all IPv6 services. Is there any existing solution? Just an idea how it could look like. It's kind of reverse NAT64/DNS64: - IPv4 clients sends an "A" DNS request for a certain service - DNS server together with NAT device tries to create a NAT mapping between a IPv4 address from the pool and real IPv6 address for that service (NAT device should check if the IPv4:Port pair is available for mapping) - DNS answer with that IPv4 address - after some time the NAT mapping is deleted and IPv4:port is now available for other IPV6 service. I don't know  if it makes any sense, but to me it looks quite interesting possible solution. thank you for suggestions and ideas! ... View more

Hi, I'm struggling with a small problem. let say we have 3 routers - R1,R2 and RR. we have 2 VRF: CustA - RD100:1 MGMT - RD:100:100 RR is a router reflector the topology looks like: I'm trying to export a cirtain routes from CustA to MGMT with help of following route-maps on router RR ip access-list standard MGMT permit 192.168.100.0 0.0.0.255 ! route-map MGMT  permit 10 match ip address MGMT set extcommunity rt  100:999 additive for the test purpose a loopback interface was configured on R1  in CustA VRF with IP from 192.168.100.0/24 subnetz. All routing information are correctly distributed over all routers,  but export  doesn't work - the IP from 192.168.100.0/24 doesn't get the additionla RT 100:999. If I configure the "export-map" in VRF configuration on R1 then the export works perfectly - 192.168.100.0/24 gets additional RT 100:999 and it's then imported by the router RR in VRF MGMT. But, as far as I understand the export should work exactly in the same way if I do it only on RR router, shouldn't it ? I mean if take a real life network - we don't want to configure that export-map on all PE routers for all VRF, it should be enough if we do it centrally - on the router-reflectors. What can be wrong with my configuration? ... View more

Hello, I see a very strange problem with our ISDN slot on c2600 and can't somehow explain it. If I connect a normal ISDN phone the line is working perfectly but if I connect  ISDN port on our router then ISDN status shows: #sh isdn status Global ISDN Switchtype = basic-net3 ISDN BRI1/0 interface         dsl 0, interface ISDN Switchtype = basic-net3     Layer 1 Status:         DEACTIVATED     Layer 2 Status:         Layer 2 NOT Activated     Layer 3 Status:         0 Active Layer 3 Call(s)     Active dsl 0 CCBs = 0     The Free Channel Mask:  0x80000003     Total Allocated ISDN CCBs = 0 and I can't start a connection, I've tried with help of "isdn test call", it shows an error like "no B chanel available" If I make an incoming call to the telephone number of that ISDN line then the status of the line changes to "MULTIPLE_FRAME_ESTABLISHED" and I can use the line just normal for Dialer connections. After some period of time (sometime is hours, sometimes is only a minutes) the Line status  goes again to "DEACTIVATED" and Dialer connection doen't work until I place an incoming call. The ISDN  Hardware is: BRI S/T - 2186 WAN daughter card         Hardware revision 1.3           Board revision A0         Serial number     19923810      Part number    800-01833-03         FRU Part Number   WIC-1B-S/T= BRI configuration: interface BRI1/0 description isdn-backup no ip address encapsulation ppp dialer pool-member 3 isdn switch-type basic-net3 isdn point-to-point-setup isdn outgoing display-ie no cdp enable router version is 2600-advipservicesk9-mz.124-2.T.bin I can see the same problem on two different locations, where we use this type of hardware. Please give some advise. may there is a kind of "keepalive" for BRI interfaces? ... View more
