Hello List, I am running FreeBSD-5.4 on my r51, While partially following (no ciso here), http://www.expresshosting.net/howto/VLAN-802.1q-Tagging-in... I sucessfully created vlan-devices and thought it to be a good idea, to give each of them a different MAC-address. now maybe that's wrong?=20 1) Is the parent interface' (em0) MAC-address required? 2) If I assign different macs, then multicast should be fine, as it operates inside the vlan's? 3) what devices are needed to simulate vlans/multicast/ospf/bgp between 3 stations? While playing around, I found 802.1q Frames running (*), but I am not sure If they are correctly working? On the other side sits a linux box 4) why cdp tells about the vlan's to the world. shouldn't it simply shutup :-) and detect/ask for cisco devices? A friend spoke of it as a newsticker. 5) can someone give me an example of using ping -I ? I get: "invalid multicast Interface ..." 6) why is multicast in mrouted(5) setup via tunnels? 7) would I need pmtu to get things working?=20 8) another question: why the hell would a printer send me icmp_redirects? 9) if two hosts belong to the same vlan, I should get a ping established between them, right? *) =20 03:24:14.785816 192.168.3.1 > 224.0.0.4: igmp dvmrp Probe [tos 0xc0] [ttl = 1] 03:24:14.785856 802.1Q vlan#105 P0 192.168.10.1 > 224.0.0.4: igmp dvmrp Pro= be [tos 0xc0] [ttl 1] 03:24:14.785890 802.1Q vlan#106 P0 192.168.20.1 > 224.0.0.4: igmp dvmrp Pro= be [tos 0xc0] [ttl 1] 03:24:14.785916 192.168.30.74 > 224.0.0.4: igmp dvmrp Probe [tos 0xc0] [tt= l 1] 03:24:14.785946 802.1Q vlan#108 P0 192.168.40.3 > 224.0.0.4: igmp dvmrp Pro= be [tos 0xc0] [ttl 1] only probes are sent out, but I expected to see 224.0.0.4 > 192.168.10.1 ... thanx for your time and best regards, wmiuser/u@netbeisser.de --Nq2Wo0NMKNjxTN9z Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) iD8DBQFCqHSPMXftaIGFSAwRAgq8AJ0Yud3nbczrd1Wqx1CirlAoAnIsMQCdGxP1 UwCw49+xc3Qb+QM812ALVX4= =1llJ -----END PGP SIGNATURE----- --Nq2Wo0NMKNjxTN9z--
