PRI [7:64999]
Hi All, Quick question I hope you can help me with. How many D channels does a PRI have? I always thought it was two, but its states 1 in most places. Text taken from the CCNP remote access guide (to make it more confusing): there are 30 timeslots, leaving 2 timeslots for signalling and framing. Timeslot 0 is used for framing and timeslot 16 is used for signalling (counting 0-31). E1 PRI makes use of this same principle. Timeslot 16 is the D channel and timeslot 0 is used for framing information. Please advise. Regards,DJ - With Yahoo!

HDLC [7:66324]
Hi, I have a couple of queries regarding HDLC and Frame Relay. I gather they're both forms of data encapsulation for data and basically this means putting the data in headers and trailers to identify to the next layer or computer how to deal with the data. Please advise whether this is correct. If this is correct, could you please advise under what circumstances HDLC and Frame Relay are used in a real world environment? Do they function in their own right, or are they part of software or hardware or a protocol? I see that HDLC is for point to point transfer only; presumably this means that if a router is using HDLC it can only talk directly to one device out a single interface but with FR, it can send frames over a LAN-like structure? I seem to be in some confusion as to where these two things fit in; the rest of the two chapters (3 and 4) seem fine, I just keep contradicting myself over these two things. I'm sure it's one of those blindingly obvious things that will be really simple to understand once someone sets me straight - I think I'm interpreting these things differently each time I read about them.

Access-list's! [7:66546]
Hi, Can someone please help on this one. We have : r2 / \ s1 server 1 -- sw1 -- r1-- --- --so- r3 -e0- sw2-- host a we want to deny host a access to server 1 on r3 we have access-list 101 deny tcp host 172.16.1.0 0.0.0.255 eq ftp access-list permit any any and on s0 we have ip access-group 101 out and on s1 we have ip access-group 101 out This is similar to a example on the ccna certification guide from Cisco Press page 506 example 8-7. Could it be done in a simpler way by applying just the one statement on e0 access-group 101 in ?? Looking forward to your comments. DJ - Yahoo!

VPN authentication [7:70186]
Hi, I hope that someone can help me with this, let me explain. We have a remote site A with isdn dialup to the coporate vpn concentrator we have a dumb box aka WYSE terminal ie thin client this is connected to a switch the switch is connected to a 1700 router with wic bri we want it to dial on demand and connect fully so the user does not see any authentication requests the user request should be done automatically but i cant find how to do that via config unless* brainstorming here* the type should be network instead of client ???

Thanks in advance for your help DJ Bosco Sachanandani wrote: >From what I understand (and have done in a similar way in my network) when the WYSE terminal sends a request for the remote host IP, and when that reaches the router, the router in trying to route the packet to the remote network (based on the routing table) will foward the packet to the ISDN interface. When the ISDN interface realises that there is a packet for the remote network, it will dial out automatically using the phone number and authentication credentails. No need for any config on the WYSE terminal.

IP addressing [7:70057]
Hi, Can someone please check below, to see if I am going in the right direction. I have 3 sites A B C A wants 500 users. B wants 2000 users c unknown up to 200 IP address range I have is as follows:- 10.225.200.0 to 10.225.219.255 I have worked the following:- For A the range is 10.225.200.0 to 10.225.201.255 with a subnet mask of 255.255.254.0 or is it 255.255.255.0 For B the range is 10.225.202.0-255 10.225.203.0-255 10.225.204.0-255 10.225.205.0-255 10.225.206.0-255 10.225.207.0-255 10.225.208.0-255 All with a subnet mask of 255.255.248.0. For C the range is 10.225.209.0-255 to 10.225.210.0-255 subnet mask of 255.255.254.0 if all on single network will all these talk without any problems and I still have 211 through to 219 free. Another quick question was should these all respond across different subnets even using OSPF or won't they. Thanks, -DJ - Yahoo!

Quick Vlan question [7:49533]
Hi, If I have two Vlans and want to route between them using an external router, but the router has only 10mb ports, how can it be done? I can't use ISL or 802.1q because it isn't supported on 10mb/s ports, correct? Does every Vlan need a separate physical connection? or do i use sub interfaces? please advise. thank you -DJ - Get a bigger mailbox -- choose a size that fits your needs. http://uk.docs.yahoo.com/mail_storage.html Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=49533&t=49533 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

OSI...Please help... [7:51235]
Please help... In the example :access-list 101 deny tcp host 172.16.3.10 172.16.1.0 0.0.0.255 eq ftpaccess-list 101 permit ip any any Do the terms "tcp" and "ip" refer to the individual protocols or the stack ? I assume they refer to the individual protocols as you could substitute them with "udp" or "icmp" but then surely the last statement would allow only the individual "ip" protocol and therefore all other packets such as tcp , udp, icmp would be filtered. Or does tcp , udp , icmp get through because it is encapsulated in ip ?

Multicast...please help [7:51822]
Hi I have a question regarding the election of the LAN router which is supposed to send the queries for multicast accesses. In chapter 8, page 302, IGMPv2 querier election, it is mentioned that the router with the lowest IP address is elected as multicast querier. In Chapter 9, page 336, it is mentioned that the DR (designated Router) elected is the one with the highest IP address. "The DR is responsible for sending IGMP host-query messages to all host on the LAN". Could you please help me understand the differences between the two above cases, because for me, routers seem to have the exactly same role but are elected an opposite way... thanks DJ - Get a bigger mailbox -- choose a size that fits your needs. http://uk.docs.yahoo.com/mail_storage.html Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=51822&t=51822 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Exam changes [7:71982]
Hi, I want to get hold of the Cisco Learning Product folders you get when you sit on a Cisco official learning course. I find them much better to read then the Cisco press books. Does anyone know if I can purchase them from anywhere, or that if they are only available when I attend a official Cisco course. The other reason is that with all the exams changing (CCNP/DP/SP), Cisco press take a while for the books to come out, but with Cisco folders you get on the course, I guess they will become available much earlier.
