来自主题: EmergingNetworking版 - 问个7600 H-VPLS的问题
就是这个上面的:
http://www.cisco.com/en/US/docs/routers/7600/install_config/12.2SX_OSM_config/mpls.html#wp1338115
Figure 1-6.
PE3 和upe之间的连接:
interface Vlan 1001
xconnect vfi Internet
这个vlan1001 没有像PE3和CE3这样:
interface GigEthernet6/1
switchport
switchport mode trunk
switchport trunk encap dot1q
switchport trunk allow vlan 211
interface Vlan 1001
xconnect vfi Internet
interface Vlan 211
xconnect vfi PE3-VPLS-A
那么vlan 1001 是怎么从access-facing interface 得到来自upe3的pw packets的呢?
换言之,在这个例子中,pe3和upe3之间的interface

在pe3 和ce 之间,
interface Vlan 211
xconnect vfi PE3-VPLS-A
vlan 211 实际和gi6/1是通过trunk port allowed vlan 211 来连接的,
这样,从gi6/1收到的vlan211的packet都会forward给int vlan 211, 然后通过vfi出去。
我的问题是在pe3和upe之间,
interface Vlan 1001
xconnect vfi Internet
这个vlan1001怎么和phisical port连起来?
因为那个physical port还要做pe3 和upe之间的mpls cloud的core facing interface,
必须要配置ip.这样就不能做trunk mode和int vlan连起来了。
你的意思是,在这种情况下,并不需要把svi 和一个physical port 连起来,
只要来自upe的同一个xconnect的packet在pe3的physical port收到后就会forward给vlan 1001,这里svi就相当于在router内部的一个AC?

来自主题: EmergingNetworking版 - 中国电信成为Nortel PBT的第一个用户了
今天training又介绍了一下PBT,据说PBT算是802.ah的一个增强。
1月份的时候IEEE已经通过加在802.ah里了。
PBT本质上就是在ethernet frame前面加了4个东西,
B-DA, B-SA, B-VID和 V-SID,在.Q bridge上用xconnect的形式传输。
通过DA和VLAN来决定路由
优点是价格比较便宜,容易实现。
用Carrier ethenet实现传输现在有3种方法,一个是PVR, BT正在用的
一个是PBT,BT将要用,还有一个就是基于MPLS的,但是相关的设备
造价比较贵。以后业界要用哪个,还有待观察。

How many ip address you have purchased?
I heard they've sent out notice to the customers about this.

They may have fully implemented the MAC Address screening.
the MAC address of the LINKSYS wan interface is registered in their access
list,
so only that MAC address is valid.

来自主题: XML版 - 哪种xml的编辑器比较好用?

The XML editor my team using is called; XML PAD, it's from MS, free
and sharp.
There is another one, from bluestone.com, called Visual XML, that's
not a simply editor, it's a complete development enviroment, it's
free. But Require high-end computer.
For me, I am using notepad.
Please note: the XML editor is using to design schema, not to input
data. Generally speaking, data is generated by program or other tools.
Like Xconnection.
