Steve, Yes, I saw that in the documentation and ran the command -- it actually gives you 2 options; either VRRP v2 (IPv4 only) or VRRP v3 (IPv4/IPv6). The command is accepted with no error. After I issued that command, I went to an SVI to start the protocol configuration, and found that the vrrp command is not available for configuration under any interfaces (SVI or routed ports). There is an fhrp command available, but it's only options are for setting timers. Thanks for the reply

I am working with a set of 3650-24TS switches, IOS XE 3.7.2E, IP Services. Feature navigator appears to say that this version of IOS XE supports VRRP and GLBP on this plaform, but I am unable to actually configure it. The configuration guides are as up to date as IOS XE 3.6. So, can someone tell me a) does this version of IOS XE on this platform support VRRP and GLBP and b) where do I find a configuration guide? The command vrrp is not available under either an SVI or a routed port. Thank You

Brian, This solution works, but it's not a very clean cut. It definitely takes the switch's ability to a/c/d VLANs away, but it doesn't update the VTP configuration. In otherwords, all the switches still show that there is a Primary server (by hostname and MAC). Odd that it wouldn't change those values. The only way I've found to change the Primary Server information in the VTP status is to have another switch claim primary status. Thanks

Hello, I haven't found a command that will do the trick. I am working with VTP version 3. I would like to promote a switch to primary for vlans, make the configuration changes needed, and them demote that switch back to a secondary server. I know that I can simply make another switch primary and it will take over, but that's not what I'm after-- the desired end-state (or in-between-configuration state) is to have all the switches in the secondary server role. Is this possible? Thanks!

I am afraid it's a 15.3 thing, but I can't find any documentation. It seemed to work on 15.2 and I know it work(s)(ed) on 12.4, as you verified in GNS3. I was hoping someone could tell me it was an unresolved bug or 'caveat' in the 15.3(2)T2 release - the release notes don't mention this at all. Thanks for taking a look though

Hello, I am having absolutely no luck making unicast EIGRP over frame relay work. (This is for training purposes, and is NOT indicative of any kind of production network. I asked the same question over on learning network and have thus far gotten no answers that fix anything). This is being done on a set of 2901's running IOS 15.3(2)T2. The frame switch is a 3745 running c3745-jk9s-mz.123-9a The scenario is that I have three routers in a hub-and-spoke network I am trying to implement unicast frame relay by setting the neighbors manually, allowing R4 and R2 to form an adjacency, even though they don't have a PVC. I put static mappings in for everyting just to eliminate any question about mapping. Here are the configurations: FRS: interface Serial3/2 description <[ S3/2 to R25 s0/0/0 ]> no ip address encapsulation frame-relay IETF clockrate 128000 frame-relay lmi-type ansi frame-relay intf-type dce frame-relay route 41 interface Serial3/3 42 frame-relay route 43 interface Serial3/4 44 ! interface Serial3/3 description <[ S3/3 to R26 s0/0/0 ]> no ip address encapsulation frame-relay IETF clockrate 128000 frame-relay lmi-type ansi frame-relay intf-type dce frame-relay route 42 interface Serial3/2 41 ! interface Serial3/4 description <[ s3/4 to R27 s0/2/0 ]> no ip address encapsulation frame-relay IETF clockrate 128000 frame-relay lmi-type ansi frame-relay intf-type dce frame-relay route 44 interface Serial3/2 43 !

I used debug ip packet with an ACL specifying R2 and R4's s0/0/0 ip address as the source and destination, and I can see that that hellos are sent from R4, I can see that R1 gets them and re-routes them to R2, but R2 NEVER sees them. EIGRP between R1-R4 and R1-R2 is working, and I can ping back and forth between the R2 and R4 interfaces. Here is R4 sending a Hello to R2 (debugging eigrp packets and frame-relay packets) Apr 2 18:35:42.847: Serial0/0/0(o): dlci 44(0x8C1), NLPID 0x3CC(IP), datagramsize 64 Apr 2 18:35:42.847: EIGRP: Sending HELLO on Se0/0/0 - paklen 20 nbr 172.16.124.2 Apr 2 18:35:42.847: AS 1, Flags 0x0:(NULL), Seq 0/0 interfaceQ 0/0 iidbQ un/rely 0/0 Here is the routing at R1 (debugging ip packets with an ACL and frame-relay packets) Apr 2 18:35:42.856: FIBipv4-packet-proc: route packet from Serial0/0/0 src 172.16.124.4 dst 172.16.124.2 Apr 2 18:35:42.856: FIBfwd-proc: packet routed by adj to Serial0/0/0 172.16.124.2 Apr 2 18:35:42.856: FIBipv4-packet-proc: packet routing succeeded Apr 2 18:35:42.856: Serial0/0/0(o): dlci 43(0x8B1), NLPID 0x3CC(IP), datagramsize 60 Apr 2 18:35:42.856: IP: s=172.16.124.4 (Serial0/0/0), d=172.16.124.2, len 60, input feature, proto=88, packet consumed, MCI Check(94), rtype 0, forus FALSE, sendself FALSE, mtu 0, fwdchk FALSE And then there is NO OUTPUT at R2 from the IP packet or frame-relay packet debugs (it's seeing the hellos from R1, but not the hellos from R4). Any suggestions would be greatly appreciated.

Here is the point I am confused on: If the phones are controlled/provisioned by CUCM, how does the router know what extension is in what group? Under CUCME or CUCME+SRST, the router knows extension numbers because of SCCP or SNAP. When the phones are controlled by CUCM, the router is just a... router. It has no intelligence about the phones. So, in effect, MoH on a branch router simply turns the router into a multicast transmitter. Here is what I am thinking, after reading more documentation... I can't lab it yet, but if you or someone else can confirm this will work or not, I would appreciate it. Under "Restrictions" at http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmemoh.html#wp1022742 it says : " Each MOH group must contain a unique flash media file name, extension numbers, and multicast destination. ....." But, Step 7 (the extenstion-range command) is listed as optional : "(Optional) Identifies MOH callers calling the extension numbers specified in a MOH group. Extension number must be in hexadecimal digits (0-9) or (A-F). Both extension numbers (starting extension and ending extension) must contain equal number of digits. Repeat this command to add additional extension ranges." What that says to me is that the extension ranges are not required, and that basically I can configure 5 groups (in addition to the system default source) with Multicast IP & Port numbers that match what CUCM will tell the phones, and it will work from there. Is that accurate? Thanks

Hello I can't find anything that says this can be done or gives an hint that configuration will support it. On my CUCM (8.6), I am using multiple audio sources for Multicast MoH. The sources are divied up based on MRGL assignments within DN settings. I would like to also stream multicast from flash at a branch router. All of the examples and discussions I've seen show a single file being streamed. I know that IOS 15 allows for 6 MoH sources (one "system" and 5 "group") to be streamed when the router is a CME router. Can these multiple streaming resources be set up when CME is not being used? I understand SRST has to be enabled no matter what; the thing I'm stuck on is if it's possible to differentiate source A from source B. When configuration CUCME (9.1 on IOS 15.2(4)M), it is possible to group phones together and point them at a particular MoH source for that group, but when using router flash for getting multicast MoH to remote CUCM-controlled phones, the ephone information isn't in the router's configuration...so there is nothing to assign to a group! So...is it possible with IOS 15 in call-manager fallback mode to specify multiple MoH sources? If so, how do you do it, and align it to the source id CUCM presents to the IP phone through it's MRGL? Thanks in advance

Thanks for the reply, but manually copying the files won't really solve the issue, or allow me to understand 'why' this is happening so that I will know how to address it in the future.

Hello, Hoping for some help here - I have tried this multiple ways but had no success I am trying to get CUCME 9.1 installed on a 2901 router. The router is running IOS 15.2(4)M2, and has the UCK9 feature permanently enabled. It has a 2GB flash drive. I have downloaded CUCME 9.1 in the form of cme-152-4Mv1.rar at least 3 times onto various Windows 7 machines and either copied the TAR directly to the flash drive or put it onto a TFTP server. The command I am using is straight out of the CME Administrator's guide " archive tar /xtract (source) (destination) Every time I try to extract the TAR file, there is an immediate " TAR Checksum Error " message, no matter the source of the file. I have used an MD5 calculator and validated the downloaded copies of the tar match the MD5 values on the web page. I have further used 7zip to extract a copy of the tarball onto my hard drive, and everything seems to extract fine - files are there and I can open and read the .txt. Any help would be greatly appreciated

Richard, Thank You. Any inkling as to why it re-orders the host statements? When I did the input, the order was 10,11,12,13. The show has it in 11,10,13,12 order. None of those addresses are more-specific, bit wise at least.... Thanks
