For u experts out there, I have 3 questions. How do u use autoinstall and avoid configuring encapsulation: Does the link experience bit errors after using autoinstall? The router on the other end send SLARPs or does it support HDLC? And do the upper layers handle error control ? I read the cisco website but it doesnt answer my questions http://www.cisco.com/univercd/cc/td/doc/product/software/ios122/122cgcr/ ffun_c/ffcprt1/fcf002.htm#33594 When do u choose IPX WAN? I know that u deploy it when bandwidth is low , but do u deploy it when there are a few routes or moderate routes or many routes? How about services? Do you deploy this when there are limited or wide variety of service types? Again I checked the cisco web but doesnt answer me. a lot of concept but not practical. http://www.cisco.com/univercd/cc/td/doc/product/wanbu/bpx8600/8_2_0/82ov er/sysmch02.htm Regarding stratacom environments how do u do out-of-band call setups?
